    As you can see from the build picture, there are cables everywhere. I want to get the machine running and use it to mill parts for my enclosure. Moreover, I want to sleeve all the cables with the exception of the one for the spindle.

    I can't wait to see a video on it running. I wanna see how the belt drive X axis works.

    I just sent G91 G0 X30 and G91 G0 Y30 and measured the distance travel in both direction and they were 30mm. I need to find a way to calibrate the z-axis.

    It can easily be calibrated using a dial indicator or a set of calipers or even using a ruler set vertically against the face but if you're using the same screw on the z-axis as the others, it will have the same input value as the others.

    First engraving test went well. Initially, the text was inverted. I had to change $3 in the configuration to fix it. I will play with the maker a couple of time before jumping to using bits.

    I have been able to get grbl to turn my spindle on and off. However, the spindle runs at the maximum rpm. Issuing the command S8000 has no effect on the speed at all. I will be glad if I can get some assistance to in setting up grbl to control the speed of the spindle. I am using bCNC. Moreover, I have attached the wiring diagram from my controller board (Phoenix) to the VFD below.

    I connected a 1K remote potentiometer, with the VFD 10v to one leg of the pot, VI to the Wiper Center leg and other leg to ACM. I was able to control the speed using the potentiometer with PD001 = 1 and PD002 = 1.

    However, once I hook up the VI and ACM to the phoenix CNC controller board, I am unable to control the spindle speed. It seems the VFD is not the problem. The problem might be the CNC controller or grbl settings. I will be glad if anyone can help with fix this issue.
