Error: All LOW and Error:Printer halted.kill() called!

Look like that was the issue. I Just reverted some lines back to their default. Thank you so much for your suggestion. As for the X-axis not working, I took off the belt to make sure it wasn't the plate. Looks like I may have been sent a faulty motor, jittering in place. Suppose I'll have to message Makertech.

As @Alex Koch mentions above, do you have TMC2208 set for all stepper motors or just the X, Y, and Z (Configuration.h)? If it's still giving you trouble try swapping to another A4988.

@Michael G did you get it working?

@Nathan Eddy Sorry I don't follow. Did I get what working? My printer is dead and is in parts salvage. I gave up on the whole exercise as I had some fun working on it but I realized that I could keep dumping money in it and I just didn't have the heart any more.

@Michael G Awww really? However, after all that comments here and at KS... can i that really understand. The presentation of the printer at KS and the real product are diffrent. Im sure Makertech had something else in mind. But the printer is really too complicated to setup. For sure no product to buy it just so for having a 3D printer.

Let me say, i don't got the Axis. I used my money (and some more money) at the end of the campaign to order the Proforge S2. I still had almost a month challenge to get it working. I had to improve a few things and have to life with some not really clever construction issues. But (BUT) it is much much easier to assemble and to program than the Axis.

I had a lot to learn. And, if Makertech is interested to improve their products, they can get plenty of input from my side.
