When using octoprint (on RPI 3B+) the exported G-code (from Luban or Cura) let the extruders run into each other. For example: a print with PETG as support (right extruder) and PLA for the object (left extruder). When the right extruder printed the first layer it stops moving and stays at the last p…

I don’t think that I have ever tried connecting Octo to the front USB port. It would be interesting to see what happens! The other thing yet to try is using Luban to upload gcode over Wifi. I haven’t done much with Luban. It looks as though it may work well for slicing, but doesn’t seem to have …

I just tried connecting my RPI with octopi to the front of the USB-A port of the Snapmaker J1, but I am not able to get connected, so I think only the USB-B port is compatible for this kind of communication. Indeed. The benefits of Octoprint for me is remote control. Using Wifi and Luban you are on…

USB-A is only for usb thumb-drive, USB-Mini-B is for serial connection, as it is at the 2.0.

I would imagine that I will be able to watch a print using my Octoprint, as the camera functions whether it is printing or not. Right now, I’m getting Luban set up to use as a slicer instead of Cura, to see what differences there are in the gcodes in generates. I’m sure I’ll still have to add M605…

Well, THAT was informative… I spent some time playing with Luban. It is not the latest version, as my Linux distro on my laptop is not up-to-date, and versions of Luban later than 4.6 won’t work. So, there’s that. Luban seems to generate G-code well enough, but I cannot find a way to insert cust…

I shared this post and my other post Octoprint and IDEX problem: extruders run into each other - #24 by MarkA121 with Snapmaker support, after they told me to ask the community for help. This was their response: “We are sorry, due to the shortage of staff in the R&D development, we are temporarily u…

Thanks for trying. I wonder if they would consider making the IDEX firmware open source, as it used to be? For now, putting the M605 commands in the right places seems to have things working well. I’m working through some issues with Cura compatibility with IDEX printers, on the Cura community fo…

Don’t know if y’all got this above in the thread, already a lot of discussion. By now you know Luban and the Cura Snapmaker plugin for the J1 use the M2000 fast tool change command? This code is interpreted by the Android firmware and not the low-level mcu. So if the code is sent directly to the m…

(Other things that only happen via screen macros include intervening with the Adjust menu, etc, and I think also the filament runout process. The screen is not aware of anything sent via the serial connection to the mcu, and vice versa, other than the displayed sensor readings. I’ve personally skipp…
