Touch plate problems and accuracy
« on: December 16, 2017, 07:25:31 PM »
Hi all. I need some help. I have 2 touch plates. 1 corner finder which works great and 1 fixed touch plate. The fixed touch plate, the tool rapids down and hits the plate, stops but does not retract to slowly come Dow for a second touch off. I have to reset mach3 and manually retract it. Does anyone have any suggestions or ideas what is happening as the corner finder works as it should. 
The other issue I am having is my machine measures correctly near the home switches but but no where else.

Are there any messages displayed when it stops?
What version of Mach3?
What macro are you using?
Are you using the parallel port? If not, which motion controller?

You didn't answer the most important question.
What macro?

I am new to cbc work. Where do I look to find out. Where is it. Some times it works and sometimes it doesn't.  I just tried it and it worked. I have noticed that when I run a g code that 1 time out of 3 times it will cut properly with no problems but i go through alot of wood.

May I suggest you read the manuals and also watch the available videos.

MAch3 does not have a touch plate macro by default, so you had to add it at some point.

Why do you want or need a touch plate?  Set up the Homing correctly, raise the Z jog over the to  starting point, lower Z until the tool is at your zero and Zero in the display?

Because it's faster, easier, and more accurate.

Thanks for the reply. I'm also having a issue with the slaving of my a to my y axis. When I Mill in climb milling the Gantry wants to go out of square causing me to loose accumulated steps. but when I do conventional milling it works perfectly.
