These are good suggestions. But not knowing his set up is hard to answerDo you have limit switches; you may need to home the machined first. Also if the soft limits are turned on and not configures correctly it may cause it to only jog in one direction.
JohnIs there a reason for stating that, or is it just like standing behind a male bovine hoping it comes out in lumps.
If a statement is made like that, it must be backed up with an explanation as to why.
Hi JohnSorry to hijack your thread M,
All I want is a basic machine that works, and the guidance I have had from a chappie that designs systems has guaranteed I will get a fully operational machine that will suit it's purpose.
John,John, please don't let a few adverse comments put you off this forum. I am with you, when people say to do this or use that it should be followed with a reason as to why it is better that way. This problem occasionally pops up with some members, but you soon learn who they are and generally ignore them.
I too want to build my own CNC mill in the future, but I'm still deciding if I will convert a small mill, or build one from scratch using linear bearings and rails as guides.
Great info thanks. I happen to have recently purchased a 4 axis kit with Breakout board with 542 controllers after I killed a Gecko 201. Nice to know I bought good affordable stuff. From memory they were only about $40 each. One day I will do something with them all.Well..
For example, a chinese 542 series stepper driver ("2M542" for example) is excellent. 50/axis.
Sometimes the cheap is good. Sometimes not.
Cheaper than a gecko (251), and better on every sense.

A lot of this stuff is very critical.
