General Mach Discussion / Re: Mach3 VB Script Help

« on: February 12, 2016, 03:37:09 AM »

You guys said G90 is abs G91 is inc so stick with one. So I should be changing my G0's to G1's and then just do .050. that now makes since to me altho why did the G0 X1*.98not work?? is it because im taking 98% of an inc move? So if I changed the first line to G90 would that equation then work?

I think you may be getting confused between G90, G91 and G0, G1 ??

I think you may also be getting confused regarding Mach3 handling equations within the Gcode line (if you are not then I certainly am).

Hi Bryan,

Welcome to the forum.

Please post your question as a New Topic, giving as much detail about your PC as you think is necessary, and I am sure someone will be able to help resolve the 'unnamed file' issue (not many members read this section which is really only for introductions rather than problem solving).

Why after
X1 GetVar(2000)
Do you have
While IsMoving()
Wend
?

It's not moving so what say do nothing wile moving

It's just one of those things you learn to love about Mach3 interpreting Cypress Enable - it is always best to tell it to wait until one operation is completed before moving on to the next (it is unimportant if anything is actually moving or not).

OK that's good to know. Now let's get back to the road runner. When I cycle start the Road Runner it appears not to be  cutting properly. When completed there is a small indent about size of a dime.  The display table looks fine and shows it cutting appropriately but my X and Y axis are not moving appropetly  to the Road Runner picture being carved. Thanks appreciate the help John is

The Gcode dimensions of the roadrunner file are in Inches and it sounds as though your machine is set-up in Millimeters.
Try editing the file and adding a G20 at the start of the roadrunner Gcode - this will tell Mach3 that you want the file processed in inches and it will then scale everything up to suit.

The Mach3 manual explains in more detail http://www.machsupport.com/help-learning/product-manuals/

Hi Daniel,

Welcome to the forum.

Post your question as a New Topic in the general section, giving as much detail about your machine and it's setup as you think may be necessary for others to understand the problem you are having. A picture of the deformed shapes you mention may also help (use the Reply tab and Additional Options to post images).

Both dependant on the overall size of the machine but…
A moving gantry machine can have a much smaller footprint.
A fixed gantry machine can have a lot less mass on the Y axis.

There are many other for’s and against’s for each design so it perhaps all comes down to personal preference.

I would use twin core braided screen similar to this pic. for all inputs (switches, estop, etc.).

My suggestion would be that you replace all your inputs wiring with shielded (screened) cable with the shield connected to a single point (star) earth at the controller end only. You should then be able to reduce your debounce setting and hopefully not have any more 'ticks' when jogging the motors.

Try reducing your Velocity and Acceleration settings in Motor Tuning by 50% for the X and Y axes, save the changes after altering each axis. If this cures the problem then fine tune your motor settings for optimum performance. The Mach3 manual gives more detailed information http://www.machsupport.com/help-learning/product-manuals/
