General Mach Discussion / Re: Spindle Orientation for tool changer

« on: November 08, 2022, 03:53:19 PM »

I dont have a servo spindle but with the VSD has sensorless vector control so I can run my spindle down to just a few Hz, I'll give your code a try on the weekend, I should be able to use the Index pulse on the encoder instead of a prox. I like your code it is nice and simple, Like usual I think I was trying to make it more complicated than it needs to be! Thanks.

General Mach Discussion / Spindle Orientation for tool changer

« on: November 06, 2022, 10:35:50 PM »

Hi all,

I am after some advice on setting up my spindle to orientate to a set position for tool changer, Back ground is I have a Zenford milling machine running Mach 3, Controller is a Ethernet smoothstepper, 1024ppr Spindle encoder wired to ESS, Fanuc spindle motor controlled by a VSD (No Positioning), & I can lock the spindle by energizing the High & low speed clutch solenoids.

My plan was to have the M19 macro run the spindle as slow as possible (20 rpm in low gear), Use the encoder for position feedback & when in position disable the spindle motor & engage the solenoids to lock in position for the tool change.

The issue I have is getting the encoder feedback to rollover or reset every revolution so I have a 0 to 360 degree spindle position, Currently the feedback continuously increments. I should be able to reference it from the Index pulse somehow, but I am unsure of the best way to proceed, Macro? Brain? is there Mach settings I am Missing? Would Mach 4 be a better option?  Any help or advice would be greatly appreciated.

General Mach Discussion / Fusion360 Plasma Post Processor

« on: June 26, 2016, 08:26:52 PM »

Does anyone have a Mach3 Plasma Post Processor for Fusion360 that they would share? I have previusly been using Lazycam with a modified Plasma Post Processor which uses a G31 & G90 command to Probe the plate & set Z height to zero. I'm keen to try the Waterjet/laser/plasma CAM feature in Fusion 360 but I need a plamsa post processor for Mach3. Any help or advice would be much appreciated.
