Ok thanks i'll e-mail the supplier and see if they can provide me with the specs and will let you know

Just found the velocity and acceleration settings in config and they are set to the default in mach3, I haven't altered them at all.

for Z axis they are...

steps per      640
velocity        799.8
Acceleration 100

Should I be dropping these figures?

Regards

is there somewhere I can just enter a figure and trial and adjust number until its right or is there a simple way I can get the figures to enter into that backlash spreadsheet?

Ok thanks for replying, its a small engraving cnc so the movement are very slow

I would think its more to do with the links, i assume they are to do with calculating how much the screw turns to move the Z axis.

I've just looked at all three links and understand what it is trying to achieve but its gone right over my head as I wouldnt have a clue on any of the figures for my machine.

Hi
 
I have machine setup fine and running ok except the Z axis has a problem.
 
I set the postion of the tool on the start position of the board and set all axis back to zero and then regenerate toolpath and press start all looks good but what happens is if the machine needs to stepdown it machines the first layer slightly deeper than told too then when it comes out of the board to the safe zone then goes back into the board to machine the next step down it’s gaining about 2-3mm each time.
 
For example.....
 
tool stepdown 1mm
 
machining 2mm deep
 
first machining 1mm deep
 
second machining deep 4-5mm
 

I also ran out a program the other day in a 12mm board and maximum depth of machining was 9mm, stepping down 1mm each time, I had to quickly stop it when the depth should have been 8mm it had started to machine through the bottom of the board so had gained 4mm

Can you suggest anything please

Building or Buying a Wood routing table.. Beginnners guide.. / increase machining area on TS3040-H80 engraver?

« on: April 22, 2013, 05:39:05 PM »

Hi has anyone here got one of these engravers and increased the size of the machining area?

I'm looking at it and thinking it only needs longer screws and could use an mdf board to increase the size of the bed  - might toy with that idea in the future

General Mach Discussion / Re: swap axis over in mach3?

« on: April 22, 2013, 05:11:02 PM »

Ok thanks, will try tomorrow, it would be nice to have the axis running the same as the one I run all day, starts messing with my brain after running a big cnc for 8 hours then coming home and my engraver is all back to front.

I've never come across a cnc running Y on the longer axis.

Cheers

General Mach Discussion / swap axis over in mach3?

« on: April 22, 2013, 04:11:09 PM »

Hi

I have bought an engraver and to me the X and Y axis are around the wrong way, they are setup as the manufacturer says with the long edge of the bed being Y and the short edge being X.

If I go into mach3 config and change the pins for X and Y will this swap them over? This would really help as the cnc's I have ever run have always been setup this way.

I uninstalled the one I had and installed the suggested one and it says demo, how do I fully register it?
