G-Code, CAD, and CAM discussions / Need help generating 3d gcode

« on: April 11, 2017, 01:12:26 AM »

Hi

can someone please help me ?

I have this 3d figure that I have had it made and have not been able to generate the proper gcode for it.

I'm trying to generate the proper gcode  in aspire but it's not coming out nicely as shown in the screens can someone please point me to a program that can do it or someone that can do it for me even if I have to pay for it ?

Thank you

Thank you Rich

yes, i thought it might be something like that, I have the idea it must work and I' guessing it'll spin as much on the laser machine as in the CNC.

Tweakie, can you please shed some light on this ?

General Mach Discussion / 4th axis question

« on: December 05, 2016, 05:23:44 PM »

Hi

I am buying a rotary for my mach 3 controlled Heiz cnc machine and would like to know if it will also work on a laser cutter.

Laser cutter has Leeto controller and supports 4th axis

Rotary seller from ebay tells me rotary will not work on laser machine and to be honest I don't understand why as the stepper motor seems identical to the cnc machine's, I thought it would be just a question of getting the right plugs and setting the parameters straight.

Can someone please tell me if it's possible or not, I'd much rather have one rotary for both machines than having to buy one for each machine

Rotary is this http://www.ebay.com/itm/262236195547 sorry if linking not allowed.

Thank you.

General Mach Discussion / Area preview

« on: May 13, 2016, 10:38:19 AM »

Hello

I am sorry if this has already been answered but after searching I found nothing, so, can someone please tell me, is there a way in Mach 3 to preview the XY area that job is going to take ?

I mean physically make the machine go around the job boundaries

I also have a laser cutter and it can be done with it and it is a nice feature, is it possible also with mach 3 ?

Thank you

Bruno

Hi Tweakie

thank you

Is it normal that the laser engraves badly on pine or plywood ?

It also engraves very well on mdf

Hi Tweakie

I have managed to ref all home but that's not exactly what I meant as the Z axis seems to go to a pre established height. I would like to to make a mechanucal template but can't find no mention of it in the manual, can you please point me to it

Regarding the laser it seems it won't engrave properly on plywood but it works flawlessly on mahogany. I tried on plywood wivarious feedrate and stepover settings and on slower feedrate ie. about 5mm sec it engraves better but leaves blank spots with nothing engraved as on faster feedrate it kind of stutters on the engraving but seems to not be leaving blank spots, really strange. Same thing happened on pine wood, can it be because these are brighter woods ?

On mahogany its perfect even on feedrate of 1000 or more, check images

Does this mean that I can't use the laser to engrave on plywood ?

Finally got it run,

thank you very much Tweakie, without you I wouldn't have made it, very grateful indeed.

Will post some pics as soon as I upload them to pc.

One question though, I want to save Z axis height as a template is there a way to do it in mach 3 ?

Now that its focused I'd like to keep this height as default because there will be jobs done with different thickness where I'll adjust Z axis height to focus laser and I want to be able to always return it to default

Hi Tweakie

I understand that with this pp file the Z axis will be static, but isn't there a distance to observe between the laser and the job to be done ?

Pardon my ignorance but what feedrate in mm/sec equals F600 ?

And regarding this PP file you sent me, is there anything else I need to do in Mach3 or Vectric or just use it as pp for the job ?

I have read the PP manual from aspire but don't really understand it tbh.

Thank you very much for your patience, really grateful

Tweakie,

Regarding this pp file, is it metric or imperial ?  My Mach 3 and vectric are metric if it makes a difference.

and can you tell me approximate values for height and feed settings for this laser ?
