Mach Screens / big tex blue tooling screen

« on: July 02, 2015, 12:25:27 AM »

I installed the blue tooling screen and it looks good, but it only uses 3/4 of the screen, I had it installed on another computer and it filled the screen. I don't remember how I got it to fill the screen could some one lead me step by step how to change the settings to use the whole screen?
Thanks

General Mach Discussion / dual x axis direct drive jumpy

« on: August 15, 2008, 05:07:04 PM »

I built a router with two direct drive stepper motors for the x axis. The machine is 10 feet long and 5 feet wide. I'm using Mach3 and a 4 axis driver from Mecntronis (easy cnc). I've set mach3 to use A axis as the slave axis of the x axis. The motors are using a timming belt systam and the dirive is direct so one revloution is 1.5 inches in the x direction. I've set it up and it cuts circles pokets and all that stuff pretty accurate but rough my y axis is an acme thread and runs about 4 reves per inch and seems smooth. The x axis is jumpy at low speed, you can hear it move it sounds like about a 30 40 herts pulse.

Is there any thing I can do to smooth this x axis out. on curves you can see each step the motor makes?
my thought is to make a couple of transmissions for the two motors so that each turns about 4 rev per in or so?
any thoughts would be appriciated.
