General Mach Discussion / Re: Y code differance

May be worth checking that you do not have a loose coupling between your motor and leadscrew (check grubscrews etc.) also check that everything else (leadscrew nut etc.) is tight.

FAQs / Re: Jerky Movement on all arc's

« on: December 06, 2012, 02:13:48 AM »

It could be related to the CAD / CAM software you are using to create the GCode. Not all software creates arcs - some just produce a series of straight lines and this could explain the jerky motion you are seeing.
Check your GCode to see if it contains any 'J' codes or perhaps zip and attach an example of your GCode.

Hi Ansen,

I am most interested in this but cannot quite see exactly what you mean by 'banding'.

I notice variations in 'shade' in the top example but it appears that not all your dots have been filled with ink.

Presumably you are producing the pattern bi-directionally and that is why you think backlash comp may help but I would like to hear more details of the problem you are seeing without backlash comp being used.

General Mach Discussion / Re: Question- How to set x,y,z directions on table

« on: December 05, 2012, 01:56:06 AM »

If you go into Config / Ports & Pins / Motor Outputs just change the 'Dir Low Active' state for the Axis in question. That will reverse the motor direction and resolve the issue.

General Mach Discussion / Re: How do I Activate and later Deactivate an unused output

« on: December 02, 2012, 04:03:25 AM »

Specifically what should the most basic VB script commands be for output 6 ON and then a later  script for OFF be.

The commands for ON and OFF...

ActivateSignal(OUTPUT6)

DeActivateSignal(OUTPUT6)

If you could attach your .xml file (it is in your Mach3 folder and named [the profile that you are using] .xml). Rename it ‘beise.xml’ click on ‘Reply’ and select ‘Additional Options’ to attach it to your reply.
This gives the information on your machine settings and may throw some light on identifying your problem.

Show"N"Tell ( What you have made with your CNC machine.) / Re: Isolation Routing PCB's and Local System Rotate.

« on: December 01, 2012, 04:24:59 AM »

I have just discovered a problem with my particular little webcam – it appears that the guts are assembled to the cable then drawn into the housing and only secured at the cable exit end. When fitted to the machine, if the cable is moved (twisted) the internal image sensor can rotate slightly thus spoiling the accuracy of the positioning / setup.

My solution was to remove (destroy) the front window, apply a couple of spots of adhesive to secure the image sensor PCB to the housing then fit a new window (it was doubtful if the existing window could be removed without damaging it). There is probably a better (easier) way to solve this problem but the image sensor PCB is now secure and all is well again.

Nice work Werner (nice toys as well  )

I am looking forward to seeing some more pictures of the laser you are constructing - nice piece of kit.
