Neat. Wi-fi would be great!

I recently used a NodeMCU for a project which is similar to the Wemos D1. Is there a shield that will make hooking up the stepper drivers to the Wemos easy? It seems it will be non-trivial and possibly a spaghetti of wires getting everything hooked up.

It’s hard to beat the plug and play simplicity of the all-in-one boards like the Rumba or MKS Gen-L.

Progress!

Switched to the MKS Base 1.4 board. Problems persisted. Realized I didn’t have a true inversion but two motors were spinning the wrong way and fighting things. Switched directions on two motors and there was some improvement. Still losing tension with a machine size of my board of 610 x 610.

Switched back to the MKS Gen-L board. Switching boards made me realize I needed to juice up the VREF on two driver boards. Some improvement.

Played around with machine size as that is all there was left really. Changed to 800. Much worse. Changed to 500. Almost perfect! Draws very well. Don’t know why, but maybe that is just my sleep addled brain from two sick kids, one who is also teething. Need to play around with that number. And connect the servo.

Anywho, I think I am missing the core concept of how the machine width works.

Having some issues with my Zarplotter.

Using a MKS Gen-L with A4988 drivers. This is one of those all-in one RAMPS clones with replaceable drivers.

I am having the same issue as Miguel earlier where X and Y are inverted. Switched motor wires around but it didn’t seem to fix the issues. Switching E0 and X makes things move in the expected direction but I assume that would introduce other issues. Not too worried about the inverted directions right now as my larger issue is that it seems to lose tension \ skip steps quickly.

I have successfully used the same board and drivers in Polargraph configuration so I believe them to be working.

Am I correct in assuming that due to the design of the motor mounts, I can put the size of the physicsal board (610mm x 610mm) into the Makelangelo software and that will be correct for machine size? Looks like the M101 then sets things correctly as +-305…

I have access to an MKS Base 1.4 RAMPS type board with integrated drivers that I may swap out to see if it works. This should rule out any board\driver issues with the Gen-L.

What are people using for acceleration and drawing speeds for the Zarplotter?

Dan,

In the Makelangelo 6 thread (https://www.marginallyclever.com/forums/topic/open-source-makelangelo-6-discussion/) you mention Miguel Sanchez and the Wemos CNCShield stuff. I believe he is the same guy who made the 4XiDraw but it used GRBL. My attempt is going to use v-slot rail and wheels and Makelangelo.

Need to finish my Zarplotter and then gather the parts for this thing to give it a go.

Thanks for the great work you do!

Thanks Dan.

Next step is to get a 32 bit version of Makelangelo going. 😉
