Park Print Head X and Y: Resting position of your nozzle when the print is paused. I just edited the gcode file to the layer I wanted, added the M600 gcode. The printer pauses at that layer, but the bed doesn't lock in position, it continues to slowly lower due to gravity. At the moment Repetier-Server is still in beta status, although there are already a lot of functions implemented and everything is running stable. However, I immediately ran into a problem:  After the reload, it wouldn’t return to the correct position on the build plate:  It was always offset by some amount. Repetier’s ‘reload filament’ code is so simple (just that one line) compared to Marlin, you can easily enough by hand go into your gcode file, find the line number like this: Or, like mentioned in the previous post, you can use your slicer software (if it supports it) to post-process the gcode to add this in where you need. But there are some good reasons to … As long as Repetier-Server is in beta status, you can use all functions without a licence key. I use slicer Repetier-Host. So that's good. And it didn't seem to be listed at all here: Of course you know far better than I what's supported. Using a ruler to measure mm is not precise enough. - pause printing and set the pause button (if present in the runtime software like Repetier or Pronterface) - remember the absolute coordinates - home the axes to prevent drooping on the object - give the user the ability to change filament On pressing the resume button at runtime, by the user, - the head will prime the extruder for 10 mm It moves the head to the front right corner where you can't get at the filament to change it. During Repetier’s ‘rehome’ operation during the reoload, it basically nukes those coordinates, thus putting an offset into my print. The settings are in mm rather than layer height! Using Cura's post processing plugin (3.5.0), printing stops, but then fails to restart. Maintaining a good balance between printing time and quality is a fundamental trade-off problem for 3D printing. For the project I am currently printing I need to embed some nuts into the project. I figured you could do the same thing in Repetier. You can follow the play-by-play on the Repetier firmware form here, but in a nutshell:  In my ‘start gcode’, I move my toolhead to the corner of my buildplate and ‘zero’ it there. Repetier is available for free, here. So must manually restart at a certain height and remove the gcode starting script on the 2nd run so nozzle does not hit the print. I noticed the pause at height plugin, which seemed very useful for this purpose. make a copy and open in a text editor. find the g code you where printing (you dont want to re-slice). Cura’s competitor, Repetier-Host, has a well functioning pause function, which works when you are wire-connected to the printer: You find the correct line (layer) in your g-code, just put ‘@pause’ command, and from the s/w user interface you define, if you wish the nozzle to move some other position while paused (preventing oozing over your printout, making room for insert placement etc. Is it possible to program a pause after printing the 2nd layer in Slic3r PE? September 2015 in Feature Requests. ), them jumps to a new spot a few cm in front of the print (no!) Seems like it should fix the 'offset' issue. and whatever is happening in that code is causing the weird offset when the print restarts based on the observed behavior? I want to swap filament colors in the middle of a build. The offset looked like nearly 20mm on Y,.... maybe 18ish. This completely stops the print, does not just pause it. I Slice with Slicer and I print with Repetier Host. If the Use adaptive slicing option is enabled, Slic3r automatically computes the individual thickness of each layer based on the angle of the surface. ), Notify me of followup comments via e-mail, Visual comparison of ballnose stepover values on the X-Carve, Building the C-Bot 3d Printer : Part 33 : Machining a mic6 aluminum removable build plate, Howto: Pause Repetier for filament reload at a specific layer number, pygame + arduino + lolshield = pylolgraph, Howto: Pause Marlin for filament reload at a specific layer number, Building the C-Bot 3d Printer : Part 32 : New Cooling Fan shroud, and bulldog clips, The fist line that says ‘STRIP’ is super important:  If you, In the STRIP line, there needs to be exactly. That did it. Marlin Pause at Layer to insert part. Al works fine after loads of finetuning. So IT IS CRUCIAL you DELETE G92 E0 (line 9 in the above picture) and instead place G92 EXXXXXXXX where XXXXXXX is, in our case, the value the print "aborted", 8027.82489. After finishing a slice, the “G-Code” is selected. I saw there is a M25 that will pause an SD print, but this is to be sent to the running machine via host software, not added to the gcode directly (since you have to unpause it manually via M24). But now it works, so we can add it to our gcode file. 1. RUN ON KILL/RUN ON PAUSE. http://forum.repetier.com/discussion/2052/lcd-change-filament-doesn-t-return-to-correct-position#latest, http://reprap.org/wiki/G-code#M600:_Filament_change_pause, https://github.com/repetier/Repetier-Firmware/wiki/G-codes, https://github.com/repetier/Repetier-Firmware/blob/master/src/ArduinoDUE/Repetier/Repetier.ino. I saw there is a M25 that will pause an SD print, but this is to be sent to the running machine via host software, not added to the gcode directly (since you have to unpause it manually via M24). This is the code generated by the slicer. I know I can program a color change in order to stop, but I need the printer to get away from the bed in order to place fabric over the print. Will check if I see something there. The external infill … If you print using Repetier-Host/server just add. 2. And via the M600 Mcode:  Up until then, whenever I’d try this code (which starts the filament reload process the LCD uses) I’d run into the exact same problem. (I did also change the Filament change z lift setting to 20 so I can have a little room to catch the new filament dribbles. add "Pause at Height for Repetier" script (with what settings?) If you firmware supports it, M600 will also pause. I add this to my Gcode at the line I want to pause\reload filament: So it does pause, do the filament change, but once again, returns to the last spot it was printing (yes! Since then I upgraded (I consider it an upgrade) to Repetier, and wanted to do the same thing. This will bring … Last year I posted Howto: Pause Marlin for filament reload at a specific layer number.. Then you can control printer through host/server until you continue. PAUSE_START_COMMANDS is used by sd card pause/continue only. Vous trouverez ci-dessous une série de conseils pour augmenter les performances d’une imprimante 3D grâce aux arrêts programmés et aux inserts métalliques. Home › Repetier-Host › Feature Requests. You can use M0 right before the start of the layer you want to pause at. From the other post issue, I'm guessing the LCD "pause for filament change" is executing M600(?) I know this has been requested before, but this "Pause on Layer" would be very helpful to those of us who would like to print multiple colors with one extruder. While unrelated to this topic, your other requests are all possible too. I hope this clears things up a bit but feel free to ask any questions you might have. M0 is the standard pause command for most Marlin machines but some will accept M600 and a lot of printers with Repetier based Firmwares will take M25. The RepRap wiki suggest using M226 to do a gcode initiated pause, but this isn't supported by Repetier, or not in that fashion:  In Repetier it's "wait for pin state". M600 would be a pause for filament change if you set it to do it on lcd. Quote; Post by Padela » Fri Oct 05, 2018 4:07 am hi to all, I need to stop printing on a certain layer in order to insert a bearing, then resume printing. ... Repetier is reported to allow a higher step rate if … Snip from last years post: I slice using Simplify3D:  In a given process, it has a section in its ‘Scripts’ tab, at the bottom, called ‘Additional terminal commands for post processing’. ... Repetier-Talk. I agree that homing is a good idea:  I was just trying to troubleshoot all possibilities of what could be causing it to fail and finally found that was it. In Repetier-Host, you just hit Pause. I know I can program a color change in order to stop, but I need the printer to get away from the bed in order to place fabric over the print. Maybe if I knew the 'pin' of the rotary encoder I could then query for it when pressed? in step 3 i found my z to be 122.1 in my g code one layer had z 121.9 and the next one 122.4 you want to delete all text before the row that say "NEW LAYER" follow by (in my case) 122.4 then save your file. I noted what layer and Z height that was, and the hardest part, I edited the Gcode manually to insert a host command. LAST BUT NOT LEAST: Note the E values increase over time, this is the absolute value of the TOTAL AMOUNT OF FILAMENT used so far from LAYER:0 to our LAYER! Only if the G-Code is selected, a file selector appears to select t… If you select the “Visualization” tab at the bottom of the editor you can select, which part you want to see. - When a stutter happens there is a short pause in motor movement, which can manifest as a blob in the perimeter, or as a shifted layer depending on other factors like speed/motor torque/acceleration settings. Basically ruining the print every time I tried. I have rebuilt my Orca v4.x to run on Arduino Mega + Ramps, with Repeiter firmware. If you want to get involved, click one of these buttons! Download files and build them with your 3D printer, laser cutter, or CNC. The G-Code editor has it’s own small toolbar, where you can select the most important functions. In Repetier host and printrun you can add commands in the gcode that only control the host software. These codes are saved as part of your current printer configuration, when you press the save button. Quick overview of the things I think are really cool in Cura 3.4. Prints that don’t require a lot of strength can get away with weaker infills like Fast Honeycomb to get a faster print. I fried my Gen6. I know that Repeteir has a reload filament option via the LCD, but it's not currently working for me: Plus, pausing via the LCD isn't accurate:  I do prints where I need absolute layer height control over the pause location. I've switched over from Marlin:  There, I could insert something like this into my gcode to trigger a pause: On restart is shoots back to the last spot it was at an keeps printing. I struggled with this for a while myself and this is the current pause code I am using to change filament on my Taz 5. Don't forget there is a buffer of commands saved on the motherboard - when you push pause in octoprint, octoprint will stop sending new print data, but depending on the complexity of the layer, and the print speed, it can take up to 1 minute for the print to stop since there is still a buffer of commands already sent to the motherboard. Now, I can reload filament successfully via the LCD. Lorsqu'un utilisateur d'une imprimante FDM 3D atteint un niveau de connaissances moyen, il cherche à accroître la complexité de ses impressions, à la fois en termes de fonctionnalité et de finition. If you want your print to be strong, choose infills like Grid, Solid Honeycomb and Triangular. This allows you to enter in script to do a text-replace in your file, to edit it for you. As it turns out you can, and actually it’s a lot easier… presuming it works in the first place: Repetier allows you to ‘Reload Filament’ via the LCD. You need to edit the gcode file after slicing to add these commands. Inserting M600 into the gcode did cause it to pause for filament change. It would be great if there was an option to set pause at layer … Pause at layer. Program a pause at a certain layer hight. So I went back into the configuration tool:  In the features tab under the "Filament Change" section, I set the "Homing after Filament Change" to "No Homing". Hello again! After opening and slicing your STL file with your preferred settings, go to Print Preview -> Edit G-Code. Long story short:  You need to configure the firmware to “not home” after filament reload. Two ways to do this: Via the online configuration tool:  In the features tab under the “Filament Change” section, I set the “Homing after Filament Change” to “No Homing”. Adaptive Slicing. However (there is always a however ) When I pause the print, to change filament, and I home some axes, th Thank you! To do the above using that system, you’d need to enter this text into that field: And (like last years post),  some really important things to note: I have been made aware that you can also do something similar via Repetier Host:  The goal of this is to print entirely untethered, with precisely defined pause-points in the code for filament change, so host software (Repetier or otherwise) is out  of the question what what I’m trying to solve. Select the number of layers to pause at. The above link has a chunk of G and M codes that could be inserted into the .gcode script at a given line number to pause it, allowing you to do a filament reload by hand. It halts the extrusion very quickly and maybe kicks the flow fan up to "freeze" the extrude at the hot end tip. I don't believe it's a 'z height added to y position' issue though : All of these tests were done on a 20mm cube, pausing at the end of layer 3, so it would have been .6mm on Z. Default is the complete code, but you can also select a single layer or multiple layers. Again, I don't wan to pause via the LCD or via a front end (S3D or Repetier Host) : I need to insert these surgically into my gcode as needed. But, the exact same problem happened after, from my other post: Upon print restart, it goes to the wrong spot on the platform to continue printing. I am running repetier .092 and the pause function is driving me crazy. For this tutorial I am using Repetier as my printer controller, as it makes it easy to pause at a specific layer. I’m try to pause at z layer or z height to change filament. Hard to get any easier. Last Post RSS roichu (@roichu) Eminent Member. In Simplify3D, you can use a script that will pause the print job and move the print head to coordinates of your choosing. The strength of your print will vary depending on what kind of internal infill you choose. "Pause at layer height" works wonderfully well now, but the "pause at mm height" doesn't work at all - it doesn't insert any code into the g-code file. All other selections are smaller codes, which are executed depending on their intention. This is inserted after the last layer you want of a certain color. During that pause I'd reload my filament. This is useful or changing the filament color, or adding parts to be captured in the print. Last Post RSS roi-f (@roi-f) Eminent Member. The above link has a chunk of G and M codes  that could be inserted into the .gcode script at a given line number to pause it, allowing you to do a filament reload by hand. This is a generic code that should work with all files. use crl+f to find the layer your print failed on (crl+f= z122). The commands I added were Gcode to move the nozzle away from the print, and a pause command for the machine.” Technical details are provided in a paper 1.. Program a pause at a certain layer hight. I have been searching, but haven't found anything. Pause at layer X code (Thanks to Virág Adorján in the Wanhao Duplicator i3 Facebook group for this tip!) I loaded the latest version of Cura (3.4.0). As you can see, you need to insert newline characters (\n) into the string you’re building for it to show up properly in the gcode later. Actually the homing is a good idea as you might change extruder position. For example, pause at the beginning of layer 10 AND once I reach 50mm of printing.
