General Mach Discussion / Need a little help please.
« on: June 04, 2016, 07:21:03 PM »
I have a Chinese CNC. I have been using it for about a year now and I will start to say I am no machinist.
I use it to engrave firearms, easy stuff manufacturing model serial number. The thing drives me crazy to say the least and I am finally breaking down and asking for help. Problems listed below
1. If I am going to touch off my tool to zero with the paper method I have to go to settings and click mm in order for it to work right. If I don't and I put the controller on (very small increments) it will travel a long way into the work surface. I have the units set to inches and do all programming in inches. If I send the unit to me it out if I don't hit mm it wil hit the limit switch and go back down.
2. I have once again tried to get the auto zero tool to work. I have the code in and it does what it is suppose to until I go to engrave. It does not travel back down to the work. it seems it does not add the thickness of the touch off pad.
3. The biggest of all of them is my stepper motors. I'm not sure I have them tuned right I keep missing steps and I have read and watched more videos than a little bit.
Thanks in advance for any help I can get I love working on the machine but it frustrates me so bad I don't enjoy it. I want to learn to do more with it.
