disclaimer first - new guy here - this is my first CNC attempt so bear with me please. Also I apologise for not attaching report - I think I forgot a usb drive in garage. Instead here's my summary of sanity checks:
I have a new Wabeco F1410 milling machine with steppers and limit switches from factory. It's a standard column type mini mill with limit switches (x on the right, y near operator, z on top of the column). From what I've been able to figure out, all tests pass - machine is precise, backlash is few microns, all axes are moving properly and according to manual (with respect to tool), tool touch off probe TT1 works and records tool offset, wireless pendant works, machine homes properly (x moves table left, y moves table towards operator, z moves head up), spindle control works well and in both directions.
Basic g1 code works and sends table/head in proper directions at proper lengths (I measured - ball screws/ratios are all set correctly).
Now time comes for first cnc program. I was following that Full Length CNC Milling Machine Training Video and have decided to make a simple version of bolt hole drilling (in air) - dry run.
Here's an intercon program:
I moved table away from x and y limits and moved head somewhere between table and limit switch - a bit closer to limit switch so that tool check operation doesn't take ages.
Then I went ahead to set a part which is basically nothing more then zeroing all axes where I brought the machine.
All good for now - time to run the program. Step one, tool change - z goes up all the way - looking good.
Cycle start and spindle starts, x moves apparently to where it should, but Z DRO suddenly changes from where it was (+43mm) to +318mm and starts mowing downwards (towards zero I believe), however that's completely wrong. If I let it go it will hit the table.
I will be able to supply report a bit later in my evening (afternoon EST) and was also planning on updating software from 4.12 to 4.20.
Thank you in advance! I'll try not to bug here and I hope I'll get a feeling for these things soon.
