Will try the DIP switches .... already had the cable plugs in/out multiple times ... SETP has been played with, both up and down .... is now back to "book value". I am thinking that if that did...

Ok ..some further information/possible clues -

The output voltage from the spindle drive controller doesn't vary ... regardless of what speed its set at. Its always around 96 volts, and I guess...

Will measure some output side voltages tomorrow.

The machine mainly does engine block machining and is setup very similar to an RMC outfit. At the time the problem started it was half way...

We are 415V 3 phase but machine is 220V. I managed to source a 3 phase transformer to drop it back to 230V or so. I notice there is a 5V deference between phases at the moment ... two are the...

That part went fine ... it was sitting very close anyway, from memory 0.1V .... but adjusted to 0v with a minute change.

Been fiddling again ... and I notice that if rpm's are at 199rpm or less,...

Ok some updates that might shed so light on whats going on ...

Regarding the vector drive accel/decel test .... I figured out I was using plug 4/pin 5 as its test reference point, instead of the...

Should have mentioned I had been into SetP and played with the parameters already ... with no change.
You say you had an AMC drive .... does that test procedure sound about right by you ?

Yes the locking arm is hammering on the indent but spindle keeps turning. Another thing its (not) doing is ... if you turn the spindle on and then command stop ... it just keeps running.

Hi, I have a problem with a 4525HT ... the spindle won't orientate. The first thing I tried was a new spindle motor encoder ... no luck there. I have done all the usual checks ... wiring...

You save the sub's number to a V variable. The program computes the number of passes as a V variable .... so you simply add the two together, transfer to an R value and add to the L ...

e.g ...

Don't worry about a reply guys .... after two days of messing about, I have figured it out ....

I have searched this forum and others but can't find an answer to this one.

A program that I created to re-machine existing parts, needs a multi-pass facing routine which was simple enough to do...

After seeking advice on which brand cnc would best suit me needs, where I live and my experience level (none, at that time) .... nearly everyone said Fadal. I am a one man business, live in a...

No, I did not take any pictures whilst doing the job, sorry. It wouldn't show much anyway as would taking some now ... just a 4" block sandwiched between column and base.

It's worth mentioning...

Just one little thing to watch out for when adding to the Y axis way cover. The risers I had cast were simple rectangular blocks, which worked fine, but the Z axis column tapers towards the...

UPDATE: Finally got around to attempting this job, having got some 4" iron risers blocks cast 6 months ago. I machined the blocks and drilled the bolt holes, then sent them out to get surface...

Yes that makes sense to me now. Thank you very much for your help !!

Ok, I can understand that and think I have my head around it now. This is probably a dumb question but I'll ask it anyway .... I assume for this to work correctly Z0 would need to be set to...

It been a LONG time since I was at school but doing a search on arctan I think you might be on the right track. Looking at a definition of what arctan is, I am probably getting the error as I'm...

One problem that could occur when using different H offsets for the same tool number is - forgetting to change back to the first operation tooling and re-running the program. Might be a good...

I have re-read the above post and think it may be a confusing/overly complicated way of explaining the problem and I'm relatively new to the CNC game .... so I'll try another way.

I am trying to...

No I didn't know you could do that ... that's perfect. Thank you !!

Can anyone help with any "simple" methods of leveling stock in Y axis terms, that is chucked in the A axis ...... using touch probe outputs/findings ?? Perhaps a better way to put it is - how...

I have a 4525HT and have some tooling that share the same tool holder (Kaiser modular type) but the tooling is either too heavy or too large to be able to be put in the tool changer.
A program...

I have been trying to set-up the 4th axis on the Z axis (i.e pointing vertically at the spindle) with intended movement being Z and 4th axis only .... but have been having issues. The program...

Great ... thank you for that, at least I know what to expect. Will let the forum know how it goes but I'm probably a month away from doing it at this stage

That is good information Rodney .... and yes I did notice a little grey epoxy sitting on the rear of the column's mating surface. I thought it was just some grey silicon sealer but if its liquid...

I have a 4525 with standard Z axis travel .... the machine was supposed to have extended Z but when it arrived it was obviously standard. Due to the logistics and cost of getting the machine here I...

Yes I did think that myself at first and ran the same machining routine, with the same machine configuration ..... but with a non Fadal posting file (I don't recall which one off hand) ... and it...

I am stuck on this one - V28 4th axis standard ..... Predator post processor and Fadal Machine ..... and this is the first time I have attempted to create a 4 axis program on it.

The problem...
