Thank for the reply. So if I click on the DR0, it change color and clear up, but remember the old value, and the I just type +12.7 ?
Thats sounds good. I thougth I maybe should use the "Goto" buttom, that I haven'nt figure out what is for yet.

General Mach Discussion / Setting new Zero.

« on: April 21, 2009, 03:42:58 AM »

I wan't to do this:

DRO state maybe:
X 124.5430
Y100.0000
Z 24.5678

I wan't to offset the Z by 20. Not temporarly.
I can do it this way: Calculate 20+24.5678=44.5678 (but if it is not 20 but 6.35 it get more tricky, and a calculater is needed.)
Or that way: G0 Z30, and the apply 20 so the DRO says 50.

But isn'nt there a way to set the DRO relativ to the current read out?

Thank you all.

Yes my costumers are only Danish at the time, and they are happy to follow there projects in danish  .

The mill is a KRESS 1050. I have good experience with the KRESS 800, so I desided to go for this one. (1050 watt)

Here is some pictures taking yesterday. Here is the KRESS mounted.

The Pink color is only protection cover.

Show"N"Tell ( Your Machines) / My new CNC mill. JEH Guitars

I have used and uses a step-four mill for manufacturing Guitars ( www.jens-h.dk)

It was beginning to be to little and slow for my needs, and there was also some issues in stability.
I desided to build my own, designed to my needs. 
Data:
X=1050mm;Y=450mm;z=150mm (can handle the outline of a guitar.)
Ball guides and ball spindels.
Feed > 5000 mm/min.
Servo motors for loops feadback (I have destroyed som guitarbodys because of losing steps) nema23 DCservo.

Here is some pictures.
The construction drawing












I have run the machine with the motors, and the axis work well up to 7000mm/min. They are very strong. I have some problems with the limits switch, but the disapear when I change cable to screened cable.
Know I only have to do the final alignments, and get to know the software.
