My K40 has nice wire management with wires tied to standoffs all over the place. Would have saved me 20 minutes.ДЄdhesion standoffs added in Mini-Gerbil kit Stupid me set them aside thinking they were just wire management standoffs and forgot about them. If you donвЂ™t want to fight the ridiculous setup I described below then AwesomeTech added 4 adhesive stand off mounts to their kit. The next thing you need to realize is that the M2Nano is mounted to studs on a plate and once you remove the nuts holding the card the studs free fall with no access to the head of the screw. There are simply SO MANY K40 variants out there it is tough to cover them all.вЂќДЇirst thing you want to do is take a clear photo of the M2 Nano so you can put it back someday if you need to. I donвЂ™t view anything as a mistake or documentation error. вЂњLet me just throw this out thereвЂ¦вЂ¦.If you bought a K40 laser and realize you need a new control card and arenвЂ™t scared in the least to change it then nothing I note here is above your skill level.

There are SO MANY K40 variants that it is hard to say that anything I took note of is a problem. I just got the card and installed it and as always took notes while doing the installation and ran into a couple of noteworthy things that I thought was worthy of a blog. There are several options out there but I went with the Mini-Gerbil from AwesomeTech. The only way to run Lightburn on a K40 is to purchase a new controller card. Most K40 lasers come with a control card called an M2Nano which is not compatible with Lightburn. No knock at all on K40 Whisperer intended.

ItвЂ™s actually pretty powerful and it really is a good hunk of software but it just isnвЂ™t Lightburn. I liked K40 Whisperer and was getting the hang of it. Most people use a free software mix for the K40 utilizing InkscapeВ and K40 WhispererВ but there is a far better software solution (not free) called Lightburn.

Gearing and half-stepping is for the next planned generation of SCARA.I recently bought a K40 Laser from OMTech.

How to solve? Gearing and half stepping, PID, or physical damping? This is seems to be a common theme!, and micro-stepping does not help (makes it worse). The arms suffer badly from under-damped motion. The controller seem more quiet but hard to tell. Nothing to do here (I think), the spindle speed range is 0 to 1000 (i.e.

The stepper drivers where set (hard-wired) to 1/16 micro-stepping.

The stepper motors are 0.9 degrees per full step. It confused me as I am used to the motors staying on. Surprisingly GRBL did not work 'out of the box', Basically, '$1=25' shut down the motors after doing a move. I am currently using a 12v 2.5A plug pack but I suspect this will be inadequate for both the motors (0.64A per phase, there are 4 phases) and the Laser (1A). It has a built in power on/off buttons which are quite handy:ДЄs my laser module has a built in power supply and only needs PWM, but this gives you the idea: Here is the controller I am using (except my is covered with labels): I thought I would buy the latest Laser CNC controller as I would like to use grbl v1.1 (my old Laser uses grbl v0.7 and is not compatible with later grbl versions). The latest is v1.1, in this version the spindle on/off and spindle speed (PWM) pins have been swapped. I have an old Laser controller but it only supports grbl up to v0.9. But I intend to convert a cartesian gCode file into a format that will fool grbl.

Grbl does not have native support for SCARA.
