yes it could be the shear pin, but it may also be a bad shear pin monitoring switch.

A good post program determines how many axis are running at the same time. the post is written to accomodate limitations of different control types. (Delcam for example) So dont get hung up about how...

your previous replys have missed an important statement you made in your symptoms.........."the program continues". It is more likely you have slippage of the axis, either belt, pulley or the motor...

as a service tec for 20 years, ive never heard of anything....they are not made of rubber. If they are stiff........change them, "Lapp" is the best cable out there.

as i said before, there are a number of possible causes.

door switch, chuck closed signal, chuck pressure switch, spindle enable relay, spindle drive output fault, no nc enable output.

check the operator door switch

is this a mill or a lathe ? there will be different causes for each

I think you loosened the PMC card when you moved the machine, turn off the machine power and then check all the boards are seated to the motherboard.

also, check all connectors are in place and...

you are both right and wrong, poly-milling is also known as polyform milling and yes, it can be achieved using x/z/c or x/y/z on a turning center.

Dont confuse this with polygon turning, for...

A lathe is programmed in two planes....X/Z, milling machines can produce 3 dimensional shapes due to the additional 3rd axis...Y, so the primary difference is 2D and 3D programming.

Also, the...

you need to find the input adresses for the encoder, slow down and stop switches for the turret, on the check page check out what inputs are active for each station normally and then what happens to...

you need to type 3 and then INIT on the program edit page, this will delete the memory, or you can use the toggle switches on the memory card. problem is, you will need to upload the parameters,...

Okuma is a better M/C tool, no doubt. More solid, better made and superior after sales support.

as a CNC service tec, I see temperature issues every day. my advise to you was based on my experiences..........I am pleased all is well now. (temp.comp is not always best way to proceed, sensors and...

does your electrical schematic show an input for this signal, I know you don't have it, but it is possible the fault input is "active". what I mean is there may be a link wire from 24vdc to this...

I suspect something has shook loose from when the new computer was fitted. the service tech needs to come back and check the connections to/from the computer.

Neutral can be used as an option on 3...

check the drive belts for condition, tension and if oily. the belts can make an awful din if in a bad way, flapping or slipping.

check the spindle encoder timing belt tension and support bearings,...

There is no mystery if the thermal compensation hardware is defective, it will cause the axis to jump around. Usually, the comp moves the axis in a plus direction because the machine is "growing" and...

No mystery, nothing clever...just :-

G code = "General Function"
M Code = "Miscellaneous Function"

always was, always will be.

Let's face one fact.........you have an alarm stating there is a fault from the spindle lub pump, how does the PLC know this? Answer, it must have an input from somewhere.

My second suggestion is...

if it has thermal compensation, try turning it off. the machine should then gradually "grow" from cold, but in a logical way. when the machine achieves optimal temperature the workpiece sizes will...

try an SKF stockist, do an internet search.

probably, there is a flow switch giving an input to the PLC. check the input, find the address in the electrical schematics (X12.6 for example). also, check if there is an in-line filter before the...

a 3 axis lathe with polyform milling and live tooling would do these parts. (X,Z,C axis)

Maybe you are not tightening up the turret bolts enough after re-alignment, check the bolts tensile strength CR ( i.e. 9.0 or 12.0 stamped on the cap head) use a torque wrench in NM or lbs/ft to...

M09 is the industry standard code for coolant off. The operators panel button probably operates the coolant valve directly, which is why the coolant turns off. M09 should reset the M07/M08 output...

only option parameters (9000's) are protected by Fanuc (Threading cycles, rigid tapping etc;) not physical hardware such as tape readers.

if you want something in a store.....you pay for it,...

Because its always done it, doesn't mean its ok.

Silly concluding remark, remember we can only give advise based on what you tell us.......what did fix it then, maybe we will do better next time.

Mazak service is also excellent..........but you didn't ask about them before.
