can anyone tell me the process In order to encapsulate a nut during the print, is it just a case of pausing the printer a the right time or is there a clever way to do this?
3DMan
It is just a case of pausing printer at the right place.
There are at least two ways doing it.
One would be to slice and let AM start sending gcode to Robox, cancel it, analyse post-processed gcode and insert special gcode command to help you with it. Yes, there is a gcode command which can help with it and I wanted to write it down but I was too lazy. It is @pete ‘s post that explained what command was. Then you find the layer and position of head you want Robox to stop and wait, insert command and tell AM to send that gcode to the printer.
Second way is to find clever way when to wait next to the printer and manually pause it (single tap to pause button on the Robox? Definitively AM pause) and resume it after you have inserted nut. One way to do so is to create object to have hidden layer with words ‘pause now’ printed so when you see printer laying filament for them pause it and insert what you need to.
I am sure people who did it will chip in and let you what they’ve done. Or just search this forum.
sounds about right.
I put a marker in the model like @click suggests, but not quite as fancy as ‘pause now’ and press the pause button. You can also move the head using the on screen controls (activated with advance mode) such that it is out of the way to insert the nut.
@3dman M1 is the GCode command to raise a pause - you can also add subsequent GCode to move the head out of the way if you chose.
In order to add to sliced GCode, you need to be on the Settings screen, as the model is pre-sliced, the Gcode (raw and AutoMaker post-processed) is temporarily stored in the user data directory - %APPDATA% on Windows. In there you will find a folder called CEL Robox\TimeCostTemp - you’re looking for the _Robox.gcode next to the .roboxprofile you wish to print with. You can open this in a GCode editor - I use Repetier Host and insert the M1 command on the layer you require. It’s best to put this after a B0 move to ensure the nozzle is closed.
Sorry if that’s a bit brief, I’m on my phone, so hopefully it makes sense!
Thanks Chris
What are chances of someone doing a step by step noddy guide?
Starting with how to show hidden files !
I have found the Normal_robox.gcode file but next to the Normal.statistics. But how do you find out which layer to stop it on?
Ive downloaded Repetier Host (looks interesting)
3DMan
An AutoMaker feature with Slicing Preview and the option to insert a Pause command (and notification via the yet-to-be-created iOS/Android Robox Control App) would be nice. In 2 years perhaps/hopefully (no sarcasm here).
@3dman actually it is a good idea. If nobody does it (and my time allows) I’ll do something like that - step by step. Only thing is that at the moment I don’t have any prints that would require so (plus I’m on Mac). I don’t mind, though, moving partial posts from this topic to roboxing.com (and/or prepare it for CEL’s support portal) and consolidating them to one article.
@dr-woo Both have been on the planned feature list for sometime - it’s just not high priority as it is predominantly for advanced users who can already achieve the same result, albeit more manually. We are currently concentrating on ensuring the already implemented features work correctly. As a sneak peak you can see the planned splitting plane/pause plane function mocked up in the screenshot below…
If possible make height togglable between mms and layer #.
I did it by creating a small boss off to the side of my model about 6mm diameter with a step down to about 3mm at the desired height. Easy to model and probably quicker and safer than playing around with G codes. I just kept checking on the print and when I noticed the printer was printing the smaller diameter of the boss I paused the print while the head was over the boss and out of the way. dropped the nut in and then resumed. worked like a charm. 🙂
Hi All
I printed a few parts with embedded nuts lately, this is how I’ve done it it worked very well.
- Installed Repetier-Host
- Save these lines of code in a batch file on your desktop. It just opens the latest *_robox.gcode you sent to the printer with Repetier.
@echo off for /f "tokens=3* delims= " %%a in ('reg query "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders" /v "Personal"') do (set mydocuments=%%a) for /f "delims=" %%i in ('dir "%mydocuments%\CEL Robox\PrintJobs" /b /ad-h /t:c /od') do set NewestAutomakerPrintjob=%%i start C:\Progra~1\Repetier-Host\RepetierHost.exe "%mydocuments%\CEL Robox\PrintJobs\%NewestAutomakerPrintjob%\%NewestAutomakerPrintjob%_robox.gcode" exit - Print the part, no support! I added some needed support to the STL with meshmixer.
- Check in Repetier (start batch file above) which layer is the first layer that starts to cover the nut. AutoMaker Layer = Repetier layer - 1
- While printing, cover the nut(s) with masking tape, the one that is made from paper, and cut it to shape. This helps adhesion, the perimeter walls don’t print on cold metal, and you can drive a screw through it without problems. Store the nut(s) inside the printing area to warm it until used.
- Be ready to pause at the previewed layer! Insert the nuts with the tweezers, resume.
- Be ready to remove some stringy stuff that comes loose at the first layer after inserting the nuts
- Wait until done 🙂
Cheers, Martin
