    I received my latest order from OpenBuilds today. The controller should work until I can create my own so having the support for additional drivers on the xpro v4 is really cool. I hope to have pictures soon and now back to working on the 3rd version of the head.

    Well due to a shipment failure I had to come up with a new idea for my controller. The xPro v4 A is NOT an A Axis but just a clone of X,Y or Z so this board was not going to work. This will however work nicely for my miniMill which will now be complete....

    Since my smoothieboard order got all messed up and cancelled I decided to figure out a plan B. I found the grbl code to add Axis C and spent the night modifying the latest 1.1g Mega release to support the C Axis. I just tested the X Axis functionality which is extremely smooth with the DM320T set at 12800 steps. Now I just need 4 more DM320T which is probably going to be a week until I receive those.

    I made progress on the smoothie board but now have this odd jitter on the X and Y axis

    Apparently the DRV8825s were not a good choice on my part as the above is a known issues with the pulses. I will try the TMC2130s as I would rather use more precision any way but the DRV8825 was just a proof of concept. until the next update....
