Hi INetCoder,

Welcome to the forum.

Excellent looking machine you have there and I look forward to seeing some pictures of the things that you make with it.

Thanks for posting the video's.

General Mach Discussion / Re: Z axis not working appropriately

« on: May 04, 2013, 07:26:52 AM »

Hi Jayybone,

I don't doubt you when you say that your system worked well in the past but there is something wrong here.

The HobbyCNC driver board expressly states that it is not suitable for use with Bipolar stepper motors yet you say that you are using it with Bipolar stepper motors. If this is truly the case then, unless you have electrically connected your motor windings into the Unipolar configuration, it is more than likely that your driver board has been damaged and this is the issue which may be causing your current problems.

Are the steppers more likely to loose steps at a given speed when wired in series rather than in parallel ?

As stepper rotational speed increases so available torque reduces. Parallel wired motors tend to have more torque at higher speed than series wired motors. There is also the mid-band resonance issue to be considered.

Probably the best information is here http://www.geckodrive.com/support.html

Hi Outlawkt,

Welcome to the forum.

Perhaps reading the manuals may be a good place to start http://www.machsupport.com/documentation.php
You won't understand it all (at least I don't) but they should give you a better understanding of the Mach3 software in general.

Ahhh - non-linear distortion - Thanks Ian.

I will crawl back under my shell.

Obviously I am missing something ‘big-time’ here but I fail to understand the complication with cutting a linearly distorted graphic.

Picture1 – Graphic as produced in CAD, complete with registration markers.

Picture 2 – Cut tool-path produced in CAM (from the original artwork) as shown in Mach3.

Picture 3 – Graphic as printed (with exaggerated linear distortion and skew).

Picture 4 – Original Mach3 cut tool-path corrected for distortion and skew (Scale & Rotation) using camera location of the 3 markers and a basic bit of high school trig.

Perhaps someone could explain…

Hi John,

If your machine has ball screws then yes you should be able to increase your velocity (in motor tuning) to 1000 and achieve faster rapids without loosing steps. However, if you have the gibs set too tight or any other binding in the drive train then this may be causing your problem.

It may just be worth connecting an analogue voltmeter across your 48V PSU output and checking that there is no voltage drop when jogging X and Y at the same time.

Anyone who is thinking of pirating this software should be shamed.
At $150 bucks or so its got to be one of the best value softwares around.
Pay the money it's worth every cent.
It's not like others which charge thousands.

Well said Al
