Mach4 General Discussion / Re: Mach4 engraving CNC laser machine missing steps and regaining them ...?

« on: July 18, 2018, 07:10:21 AM »

I have already seen this in the Gcode file (the missing letters), and other Gcode files with text in them,  why does aspire calculates it in this way, or is it the postprocessor ...?

Who knows, the way in which Aspire creates it's toolpath is a mystery to me.

why is the M62 M63 an advantage ? 

Those commands have been specially created for laser use, taking effect at the instant of axis movement, and performing a better job with Mach4 than an axis direction pin.

I will look into you postprocessor

My post processor was just for inserting the M62/M63 commands it will not create a different toolpath or workflow.

I only ran a small portion of your Gcode and it is not good.

Your Gcode consists of too many short segment moves and missed letters (which are returned to later in the Gcode for completion of the word). If you did, for any reason, miss a step or two this could explain the transposed letters.

I think that if you improved your Gcode compilation you would not be having this problem.

You may also want to look at using the M62/M63 commands for switching the laser Output# rather than the Z axis direction pin. If it's any help to you my Vectric / Mach4 / Laser post processor is here; https://www.machsupport.com/forum/index.php/topic,36640.0.html

Looking again at your pic. in more detail I see you have more instances of transposed letters and I am inclined to suspect the Gcode.
If you attach your problem Gcode I will run it here and see if I can replicate the result.

I have absolutely no idea what is causing this but what is really weird is the C and y transposed (in the centre circled example). Obviously, that could not be caused by 'missed steps' so something is going on with Mach4. Are you using the M62/M63 commands for switching your laser ?

General Mach Discussion / Re: Configuring a light curtain for a CNC router

« on: July 16, 2018, 05:42:03 AM »

There are dangers with operating any form of equipment and you perhaps need to decide just how safe you need to make your machine environment.

If you or any part of you is inside the curtain at any time whilst the machine is active then you are not ‘totally safe’.
Even at (perhaps ‘especially at’) limited, slow speeds the available torque of any axis could still cause substantial personal injury.

I take a ‘calculated risk’ when operating my machines. I have an Emergency Stop (which instantly disconnects power to all parts of the machine and accessories but not the PC) and a dry powder Fire Extinguisher (especially for laser work) within easy reach at all times. Third parties and pets are not allowed anywhere near an operating machine. So far, this has served me well but, as you can see, it is not foolproof and it is not totally safe.

Not much help to you but due to the shrouded nature of any available information from Boxford when I converted my VMC all the existing electronics (except the VFD) were discarded in favour of the more modern stepper drivers, etc.

There are a number of issues with version .066 and this may be one of them. Try using version R3.043.062 which can be downloaded from here; http://www.machsupport.com/software/downloads-updates/   (it can be installed over the top of your existing version).

Hi Seregius,

Why not talk to Artsoft / NFS directly about the problems you see with Mach4. They can be easily contacted by the ticket system here;  http://www.machsupport.com/support/

I think you need to reinstall Mach3 as something has gone wrong with your installation.

(The atl71.dll should be in your Mach3 folder - a copy is attached if it is any help to you).
