hi guys
we lost the hard drive and have rebuilt it with a lot of help from mr Laurent,
we have 2 final problems remaining:
1) when running dry run to check the program the spindle turns on , the dry run led is on (AUX 1).
2) rapid speed is quite slow in relation to what it was
any help greatly appreciated
report is attached

Re: mpu11 machine
Short answers:
(1) The CNC program you posted, written out by the "mpu11wheeldig.txt" file currently on your control, assumes that PLC bit MEM72 (CNC variable #70072) will indicate when dry run mode is active. However, your PLC program sets MEM58 (CNC variable #70058) to indicate dry run mode. It is likely that your PLC program is newer, and your mpu11wheeldig.txt file is out of date. However, it is going to take a little more expert attention to ensure you have a set of files that are compatible with each other.
(2) Your rapid rates are set to 6000 mm/min. While not blazingly fast, that does not seem unreasonable. If at times you see supposed rapid moves going much slower, that may be because of the door switch (see Parameter 85 and INP15). If your rapid rates were previously higher than 6000 mm/min, you can probably increase them again. If you start getting "410 ... position error" stalls during rapid moves, then you increased them too much.

Re: mpu11 machine
Thanks so much . I did see the mem58 reference in the files but don't have the programming knowledge to change it.
In the g28 movement it travels at about 1000mm per minute.
Can I get some expert assistance to check over the files please.

Re: mpu11 machine
Update
1) modified mpu11wheeldig.txt to look at mem58 and not mem72 and now dry run works.
2) yes it was the door switch slowing rapid moves.
Still left with 2 problems
1)When setting up probing if you touch the probe off the part it cancels the job . We used to touch the part and back off to get an exact position.
2) in dry run it used to have an offset , x and z backed away about 1 mm to visually check the job before cutting, this offset is not active anymore. Any suggestions
Would it be possible to modify the mpu11wheeldig.txt to make multiple passes ? Like 2 rough passes and a final cut
