I got this from polabs

We are in contact with Mach4 team on how to solve this issue and implement real-time outputs control.



 So you were right

i will check it,  but i don't think the gcode M62-63  has ennything to do with the pokeys 57cnc   it is in mach 4  ....?

mach 4 reads the M62-63  an just puts this to an output of the pokeys....

i'm using the pokeys 57 CNC

But the i also trie this in MDI
G00 X20
M62 P1
G00 X0
M63 P1


and the output stays high all the way tru....?

I have tried this and mapped an output of my pokeys to output 1  but it just stays high.  can see this in de machine diag.


any sugestions..

i have added the G-code file

Do you know how the setup mach4 to use these commands ...?

Thanksfor the fast usefull reply

I ineed had a problem in this engraving with missed steps,  now it al makes sense   thanks.

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 ...?

I don't think i can do annything about this ....? (exept for the postprocessor...?)


I will look into you postprocessor   why is the M62 M63 an advantage ? 

thanks,
Bart

Hi,  thanks for you reply!

I used missing steps in my discription, because i don't know how else to call it ....

But like you say,  looks more like a software bug maybe ... I have checked the preview window in mach 4 and there everyting is like it should be.

No i have mapped a second motor to the Z axis, and use the direction pin to fire the laser...

I have attached the gcode file,  it is a lage file of 21Mb and it runs for about 3 hours....

Did a test in the air this morning (no engraving just the movements) and my origin is exactly the same in the end of this program.

will do an other test tis evening with the laser on...

Hi all,

I'm having some problems with my CNC machine.

I have attatched a picture of some engraving work.

You can see in the circles that sometimes there is a wierd space between some of the letters.
It seems to be always to the X- direction,  but the sapce is not always the same.   Looks like missing steps to me, but the strange thing about it is that the name he does next is in the place it should be, and with no spaces ....

the Gcode seems to be fine when i generate it in Aspire 8.5  and also when i load it into mach 4


Anny idea's on this ?

Thanks,
Bart

CNCman,

sound perfect,  but do you know where we can find some examples of such a LUA code,  because i don't have a clue to start on this ....?


Thanks,
Bart

I'm looking for the same thing but also can't find any info....


I did not test it yet, but i think you can use an encoder his A signal to make the feedrate go up,  but if you then use singal B to lower the feedrate,  this will not work because of the both signal that are comming in together (at differerent times but ...)
you could maybe plate a button between the B signal, but then you can just as easy place  2 separate buttons for up and down...

If I don't find a solution fast,  i'm planning on putting a rocker switch with a lever that has 2 mono stable positions, so you can push it up ar down to change the feedrate...



(I don't have anny knowledge about the programming for mach4  (at this time))
