Excellent work Hood.

I think rapid moves with the Haimer in the chuck is real scary to watch.

Hi Mitch,

Assuming you are using the Parallel Port then it may just be worth checking the voltage between an LPT axis Direction Signal pin and GND (pin 25) whilst jogging that axis in each direction.
The newer Parallel Ports use 3.3 Volt TTL logic and many of the cheap Chinese controllers like to see the older 5 Volt TTL logic signals.

General Mach Discussion / Re: Jerky Motion 5 Axis Mill........(sound familiar?)

Hi Matt,

It could well be your BobCad generated GCode which is creating the jerky motion (perhaps if you zip and attach your GCode file others could test it and confirm one way or the other ?). Perhaps also attach your current profile .xml file then it can be established if you have any Mach3 setup issues.

Try clicking the Regen. Toolpath button - this always seemed to work for me.

Hi Chris,

My guess is that your GCode is OK and that your Steps per Unit have been set incorrectly in Motor Tuning.

It is perhaps best to calculate the steps as per your equipment and Al's calculator can help http://www.machsupport.com/forum/index.php/topic,16315.0.html
Alternately, you could use the Mach3 Axis calibration feature (Settings page).

Hi Tony,

It would be best if you post your question as a new topic in the General section where it will get more attention and hopefully some suggestions towards resolving your problem (this area is just for introductions).

General Mach Discussion / Re: Help with Mach 3

« on: August 28, 2013, 03:36:40 AM »

Hi Chris,

Not sure if this is any help to you or not…

I machine many circuit boards and often use different CAD/CAM software to create the layouts. As the problem of scale is always a possibility I now include in the layout an outside border, of known dimension, around the pcb (or two outside markers of known distance).
Once the GCode has been loaded into Mach3 the Toolpath tab shows the Program Limits (size of my border or distance between markers) I then, if necessary, adjust the X and Y Scale DRO’s (main screen) to get the size correct (just a simple calculation required here).
