Help on Building CNC using Arduino Nano + CNC Shield v4

Hey Guys!

I converted my laser plotter ( ortur ) into a simple pen plotter. I originally used ELEKSMAKER MANA SE V3.2 board (XY axis + servo motor). But the problem is that the motors were soo hot to touch and burnt my stocks of servo motors ( from cheap to expensive ).

So I decided to replace it with Arduino Nano + CNC Shield v4 and 3 stepper motors (nema 17) + 2 endstops for XY axis only.

Installation part was cool. And test run the machine using UGS without editing the settings. Motor sounds good and smooth sailing. The problem started after I modified the $100 and $101 values to their correct steps. Now, the motor runs like it's dragging something and its loud.

Thanks for the report. Please come back and tell how it developes OR

You forgot inflation? :wink:

usually "CNC Shield v4" have design flaw so microstepping not applied and in GRBL FW must be Step and Dir pins swapped.

Done that part but still the same. Ordered new shield v4 board, modified it and it's working fine now. But later upgraded to MKS DLC32 v2.1 (without screen)

I'm now using it to pen plotting, laser engraving, cut stickers and a bit of cnc using 775 motor.

how are you liking this?

I have an eleksmaker a3 clone that I really really want home switches for. don't need Z.

running a 500mw laser, might upgrade to a 2500 or 5000w

love the MKS DLC.

i used the original ortur laser master 2 frame instead of the ELEKSMAKER A3 frame. 3D-printed parts to replace those acrylic ones, and some additional parts to make changing heads (laser, pen and cutter) with ease.
