Is there a k40 that can be used with lightburn without replacing the motherboard? It’s troublesome for a novice to change the motherboard.
MeerK40t can pretend to be a Ruida controller and translate to other kinds of control boards that have shipped with K40s like M2 Nano, the old Moshiboard controllers, and now the new M3 Nano. Lightburn is configured to talk to a Ruida controller and pointed at MeerK40t, which understands the Ruida protocol and translates it for the other controllers.
Ha! As usual my timing is perfect. I was running MeerK40t on a little Raspberry Pi 4 for the last year but just ripped everything apart to replace my motherboard.
Oh well. Good learning exercise.
If you order your machine from OMTech, for an additional fee, they can upgrade the mainboard to a Lightburn compatible one. I’m unsure of the logistics, but if you ask them when ordering, I’m sure they can sort it for you.
I found this video which explains how to use lightburn via meek40t lightburn on m2nano k40 Glad I found this forum and thank to Mcdanli as this lead me to the video. This will save a lot of money as I will hopefully not have to replace the k40 m2nano motherboard.
@Tatarize gets the credit here! I just spread the news.
As far as I know, he really had the key insight that the m2 nano is actually pretty smart engineering for a motion control offload board. This is essentially the same architectural pattern as the Klipper 3D printing firmware that has been growing in popularity.
Yeah, also a lot of MeerK40t is intended to be really good software and useful. So while it might not be there yet, the idea of making some really solid software for the default board is a major point behind MeerK40t proper. There’s also grblcontrol though I’m not sure if I fully tested it last version or whatever. It might be better since the Ruida bit in lightburn costs more. And there’s a lot of other bits of software that generally work with grbl protocols.
Oh, dang. I didn’t know MeerK40t existed. That’s a neat hack.
