Hi Rasta, I had the same problem and discovered that this happened when fast jogging with the outer ring and accidentally turn the fine positioning jog knob.

General Mach Discussion / Re: Slaved servo motor not following master after stop

« on: May 25, 2019, 07:59:51 AM »

Hi Russ, actually I am still finishing it off but this happens when I press home all axis and stop it  somewhere in between before homing. I havent yet tryed it out with ana actual cutting path but I think it's about time I give it a try to see if this could happen. I will also be installing a light sensor across the gantry so as to trigger the e stop when this happens.
When this happens all servo drives are still functioning and no warnings are displayed on the screen, I am not sure if anything shows in the diagnostics screen but I have a look. The only thing to get it running properly is a restart.
Thanks Marten

General Mach Discussion / Slaved servo motor not following master after stop

« on: May 24, 2019, 04:46:51 PM »

Hi guys, I'm having issues with  the A axis servo which is slaved to the X servo. After starting up both themachine and Mach3 everything works fine and all movements back and forth behave as intended, either through keyboard, joystick or pendant, but after pressing the stop button there is absolutely no movement of the slaved axis A. I have encoders on all 4 servos and was wondering if someone on the forum has ever encountered this sorth of problem. I currently have Mach3 version .43 installed so I don't know if an upgrade of the software rectifies the problem. I haven't updated yet for the reason that I am happy how it's working exept for this problem.
Any recommendations please?
Thanks Marten

Hi guys, ..... first of all I'd like to send my greetings for the festive season to all you people who make up this great family.
So, after some while on radio silence, I've been doing work on my second build and as promised attached are some photos of my progress so far. Nothing out of this world but if this gives ideas tto other poeple then the purpose of sharing would have been reached.
So far I have installed all servo motors, homing and limit switches, drivers electrical system, lubricating tubes to all ball and linear bearings. The 130W laser is on its way and is due to arrive in mid / end February along with the power supply, cooling temperature controller and the whole lot.
Furthermore I've done a dry run and checked the total working volume and all is so far as planned.
Anyway below are the pics.
Regards
Marting

Wmgeorge,Since I have no experience with laser yet, I stand to be corrected on the following......could it be that you may have been running the cnc through  a printer port ? If so, could this be limiting the response speed?

Hi Wmgeorge,
Thanks for the feedback, much appreciated particularly with the issue of engraving with Mach3. Would you care to elaborate a bit more what the issues might be / are? Originally my plan was to cut 6 to 10mm thickness in wood and similar materials, plastics (naturally excluding those containing chloride) etc.Further considering future projects with anodised aluminium requiring engraving, have made me decide to go for the 130w laser.

I only use Mach3 as an intermediate program between a cam programm and the cnc, so the way I see it (and I stand to be corrected here) there shouldn't be any issues unless if these are related to the postprocessor. So far I have engraved on irregular surfaces with a V cutter and never had any issues with the results, hence  would very much welcome any eye openers.
Thanks Marting

Hi Tweakie,
Thanks for the information, I still have a long way to go until I finish. Although I had planned to install a laser from the beginning, I haven't given it that much thought but since I've started enquiries I need to know what I need to order and where to install it and so this is the right time to take it in consideration. Attached is a photo of my progress so far.

Regards
Marting

Also would be adopting a similar setup as yours Tweakie, but still have to figure out how to keep out the dust but mostly to come to terms with the risk of vibrations. Truth be told ,I will be fixing the laser to the upper part frame (as it will be enclosed to contain dust) of the cnc and suspened on shock absorbers, but on the other hand experience thought me never to under estimate what nature can do from behind your back without noticing whats going on. Anyway I'll have to see.
Thanks

Ok. So I've done some research and read most of the thead you suggested.  It turns out that from a 40W laser I'm intrigued to step it up to 130W since the prices don't defer that much. Anyway from the information I searched the later can easily cut 15mm thick wood and polycarbonate. While I was at it I started wondering if with much power I could engrave on anodized aluminium since I have some projects that I intend to do in aluminium and have them anodized.  Any experience with the later?
Thanks

Hi Tweakie,
Thanks for the information,  yes the up side of co2's that they are cheaper. The main thing that concerns me most of all are the vibrations that may cause damage, since I have in mind to run it both as router and laser. I still have to figure out if this is the ideal situation (on one side having saw dust while on the other clean mirrors is a must) and if so how to go about it.
