Feature Requests / Mill setup config for Y axis movement type

« on: November 06, 2018, 09:58:56 AM »

There is a fundamental difference between having a moving tool for Y axis travel, or moving the work piece past the tool.
Having a moving work piece changes the orientation of the tool path display so everything is backwards compared to the default configuration.
Can there be a selection for tool travel vs work piece travel? 
On my machine the Y axis is set up for Y+ moves the work to the front of the machine, Y- moves the work to the back.

Mach4 General Discussion / Feed rate not steady

« on: February 10, 2018, 06:46:44 AM »

I'm setting up a control box and configuring the motors for a small mill, and I noticed that when I give a command for movement the feed rate readout is not a steady value. The rate changes with FRO slider and feed rate command, but it fluctuates about the desired value when driving. The sound of the motor is not steady, and the feed rate readout is jumping around for some reason.
From a knube pov I thought the feed rate would be a fixed value.  What would modify a simple feed rate output?
The motors are set for 60 in/ min with an acceleration of 4.0 and 2032 steps per unit.

I made some boxes to neaten up the stepper motor wiring, and be able to use 3/8 greenfield conduit to the control box.
It uses a plug connector for a splice block.
