Hey guys. Its been awhile since Ive posted. Built my first machine four years ago and with all your guys help it was great!!!!! Things progressed and I quickly out grew my machine capabilities.(over a period of a few years) Hence I debated building a much larger machine myself or purchasing one. After much debate and time being a huge factor, I decided to order a Chinese machine. I saw the machine in person before I ordered and felt very good about the mechanical soundness of it. With mach3 being viable option it became a no brainer for me. I knew there would be some issues to work through, but after setting one up from scratch(With the help of all of you
I was ready for the challenge. I got my machine last week. It is a servo machine with an hsd spindle. The usb control board is an XHC-MK3 and the spindle is driven by a Delta VFD. I built my own pc and set Mach3 up on it. The manufacturer sent me an xml file, but it was in metric. Spent a few hours on the web but finally found the plugin file that I needed for the external motion controller.(New machine usb not parallel port like the one I built) I converted the xml file from mm to in, loaded all the plugins, and had manual motion much quick than I expected. Had several issues with homing. Finally went to single stage homing vs dual in the plugin in file and it quit blowing past the home switches. Only axis I could run dual stage on was Z. Still pondering over that one. After calibration and soft limit setup I was finally ready to run a test program. Slowed everything down and away I went. Next set of problems!!!! Spindle starts comes up to speed, program takes off, and somewhere in the process the spindle just stops!!!!! No input flickers on diagnostics screen. Output to spindle is still showing on. Tonight I done a couple of tests. I turned the spindle on manually and just let it run. After that I started jogging each axis manually to see if I could make the spindle stop. The whole time I was watching the diagnostic screen for flickers. I originally thought it could be interference, but never saw anything. All servo cables are shielded and grounded as well as the spindle cable. The spindle would stop after jogging awhile. The output for the spindle remained on. I did notice that when this happened I temporarily lost jog function of the wireless pendant as well. I put a wireless pendant on the machine I built, but preferred the original shuttle setup I had much better. It just didn't last long when being bounced on the concrete a few times. I am going to attach my xml and the plugin file for the bob. At this point I feel like I've missed something in the settings or there are some issues with the plugins. I have realized that after four years I am not as familiar with all of this as I once was. I haven't dug in to any of the vfd settings either. I do know for a fact that there have been problems with the bobs on some of these machines. I have no problem with upgrading to a better board, but don't want to start jumping to conclusions until I'm sure that I have not missed something simple. Any help from you guys would be greatly appreciated.
