General Mach Discussion / Mach 3 backlash and circular interpolation

« on: June 13, 2020, 10:26:13 PM »

My holes are coming out oblong, backlash is set up correctly, and the only thing I can think of is try and reduce the backlash on the machine as opposed to just using the backlash compensation in Mach 3, but was wondering if there's anything else I could do?

Show"N"Tell ( Your Machines) / My Harbor Freight Mini Mill CNC

« on: May 24, 2020, 07:38:16 AM »

As pictured, my harbor freight mini mill converted to CNC, I want to add a coolant mist sprayer for my machine but I'm afraid of rust on my ball crews, I installed a plexiglass shield in-between the motor and the column to protect my Z ball screw and ball nut from any flying chips, I also installed a piece waterproof fabric to act as one large bellow to protect my X/Y stepper motors from any future coolant.

Any ideas on what to use as coolant on the cheap? And I've been using a heat lamp 24/7 to keep any and all humidity down to prevent any rusting. Any advice or opinions will be nice.

Thanks.

Mach4 General Discussion / Mach 4 setting up software I/O.

« on: May 18, 2020, 11:56:08 AM »

Hi I'm trying to figure out how to setup the mach 4 system and the whole setting up the I/O is confusing, I'm using this stepper motor and driver kit from eBay. https://www.ebay.com/itm/151796936792
I'm using a UC100 motion controller.

The pictures here show what I have absolutely no clue on what to do.
Don't know what pin is for what, don't know what exactly to enable or don't.

Thanks for any help.
