Hello, I seem to be losing steps in my Z axiis, as it begins to cut, it starts out fine and as it continues on the material it starts to go deeper and deeper into the material. I am using 1/4 x 20 rod on my axis's and on the z I have it set for 8000 ex 15 and 7 I am in the process of rebuilding a new machine with much better materials and equipment, They should never tell any beginner to build one of these out of MDF board it turns out to be a waste of time and money.so if you can let me know what i can do to fix this problem i wouls appreciate it.
Thanks
