I decided to install the CM .364 Build tonight and start exercising my new Turlen Dial indicator. I want to know how true my custom T-Nut’d wasteboard sits in refernce to Z heights.
The CM Rapid Positioning utility is a great way to move about the machine bed and get some good measurements, When I click to position along the most negative, left X position, the Z carriage smacks against the left side rail (this after successful homing) and chatters for a few cycles.
My question, are the current 850mm X/Y extent correct, or does this need fine tuning?
I jogged mine manually from the home position until it was almost to the left end plate, then used the distance shown on the screen that it traveled. So I used 838mm (32.9921 inches) rather than 850mm.
I am having the same trouble. I first had my extents set to 850 and 850, all was well. Now for some unknown reason, every time I go to any of the LH side Rapid Positions the gantry will hit the rail. I have tried adjusting the $130 to everything from 830 to 850 with the same results, like the setting is not taking. Have turned off the machine, re-homed, etc. Anybody else?
