I am disappointed... You have not seen my videos. Then you would know that, I use ESTLCAM and not GRBL. So I can't help you.

Everything I want to mill, I draw in Photoshop, convert in Adobe Illustrator, add in Fusion 360 and mill with Estelcam.

I am a graphic designer (Surfaces design), so I know a little bit about drawing programs. I taught myself Fusion 360 and Estecam while waiting for the 3d printer and parts from China.

Actually I knew that you are using Estlcam but I thought it was a GRBL software like. But I see that Estlcam uploads his own firmware on Arduino UNO using GRBL.

No worries, I will ask on another thread in order to not polute yours or maybe I will switch on Estlcam directly (I like the gamepad)

Don't be disappointed, the all family and I watch your videos every evening. Am I exaggerating ? just a little 😎

Thanks

Hello, Kamil

Your job is extraordinary! I will venture to perform the Heavy CNC with your update. Would you give me the link to your entire project?... Thank you.

Hello Kamil,

One more question for you regarding the optical endstops, how did you wire the (VCC, Gnd & Signal) onto the CNC shield?

Thank you

Ready

On the black and white bar on the right side of the shield, the upper ones are reserved for endstops. There you connect signal to white and GRD to black. VCC is 5V, you take the left top blue / yellow bar lowest pin (blue) is 5v on it. Keep in mind that only three axes are controlled, they are not divided into X 1 and X2 or Y1 and Y2, but only X Y and Z. So you can save a lot of cables.

Thank you for this clarification Kamil.

Do I understand you right that only one signal of one endstop is connected to the shield per each axis but the second endstop of the same axis can be connected directly in parallel to the first one and do not need to go to the shield?

Exactly that. You can take 1x GRD, 1x 5v for all axes and 1x signal per axis. If I had thought about this before, I could have saved many cables.

And do not forget. You also need mass GRD for tool length measurement.
