My X axis encoder on a 94 vf2 seems to be acting up, no errors but it will lose/gain a few tenths upto 0.0015 just going back and forth. Cleaned brushes and motor, motor looks ok.

Original (not...

Started getting what looks X axis drift towards (-) on an old brush motor VF2. Milling a pocket with sideways hatch and finish pass, finish pass on (+) side does not line up. X axis drifted to (-)

Getting an A axis fault on a '99 VF-5. Tried swapping A and Z axis servo drives, still alarms A axis fault with either drive. This happens towards the end of the program after running all axis fine...

Looking to build a small diy waterjet, so far have an ingersoll 40hp 55k PSI intensifier and some plumbing but looking for a cutting head. Applied science had a youtube video of a pressure washer...

Thank you, according to fagor's site they do not support it anymore. I don't think its physical wiring or it would not move at all either with MPG or in the small steps. Output module from real time...

Yes, unfortunately same problem. Also tried running programs left by the previous owner, same problem. Feed rate knob works, if I set feed higher it will move faster and further at each start / stop...

Trying to get a new to me machine with a Fagor 8025T going. Axis will jog but not move in automatic mode.

Any simple program the machine will load, start spindle but NO axis motion (just sits...

I have an HSD spindle salvaged from a pile of surplus, rated for 380v 100-300hz. I only have 230v 3ph and a 460v transformer available. VFD is rated 380-480v and will supply the correct freq range.

Looking for a manual (or at least pinouts) for a A06B-6050-H402 3 axis servo drive.
Planning to use it in a machine build with mesa cards, hopefully it is 0-10v analog but I do not have pin-outs...

Looking for a manual / pinouts for servo amp A06B-6050-H102 or anything from the A06B-6050 line (analog). If anyone has one for download or sale, I have not yet tried fanuc as they are probably too...

Unfortunately it is 19pin , so that means absolute encoders? Do you know where to find pinouts? I have not yet taken off the encoder cover, and there is no part no. (other than the motor) on the...

I don't know if the encoder is abs or not. Unfortunately the only spec I have is a PDF I got searching the forum, it breaks down all the motor part numbers.

For all the other encoders it lists...

Motor is:

40S/2000
A06B-0583-B065#7000

I don't have a drive yet, that is what I am trying to find.

I looked the at pico systems fanuc converter but it's max resolution is listed as 10k p/r...

This is a 7kw motor, I would like to have close to full power. Application is basically a turning C-axis so it has to be closed loop. It will have to switch between turning (dumb) and then index or...

I have an old fanuc servo I would like to use but need to find an appropriate servo amp, motor is:

40S/2000
A06B-0583-B065#7000

Searching the forum I found some fanuc data sheets which say the...

I don't want to get bigger stepper motors yet :) I am about maxed out for feed rate already. I could reduce RPM but the spindle is only 600W, wouldn't I lose torque by slowing it down with a triac...

I have just started working with wood on my DIY machine, so far mostly hard woods (birch, oak, ash and tigerwood). At the moment I am running a 4fl 1/8 endmill, the same as I have used for aluminum...

I have 2 of these. Build quality is good. Bearings are a bit iffy. They do not look that great when taken apart. The chuck asssembly will slip the bit upwards under higher step-down load. Even fully...

So far I have about 110in on the 4fl at 5k PRM and its still working. The lower part has dulled slightly which is noticeable on entry into the metal.

Temperature of the mills (stop mill, stop...

Thank you all for the advice.

I have lowered the RPM to around 5K, not really sure since it is dimmer style control and I have no tach. Switched to a 4 flute slotted endmill (not by choice since...

I am trying to cut 1mm sheet steel (alloy not known) using a 1/8 2fl end mill. Currently at 20k RPM and 180mm/min (~7in/min) under flood cooling of soapy water.

The endmill will last about 2.5m...

Hmm... tried a larger diameter cricle and reduced arc factor to 0.5, there are sill jaggies but more of them. With 3in diameter backlash does not seem to be the problem, the circle closes and remains...

The jaggies look like smaller arcs peaking into the circle on the cutout. 3 of them in the middle of each arch. The roundness of the cutout appears ok. They are symmetrical and there was no...

Not set at the moment. How would I determine amount of X and Y backlash to compensate for? To the touch there does not appear to be anything.

I am getting jagged edges on arcs from turboCNC and a hobbyCNC board. For a simple test I tried 2 arcs forming a circle manually in G-code. It ends up with 4 symmetrical jagged spots, however the...

Hmm, I have tried cutting AL with 2 flute and 4flute cutters (0.05-0.125) and it makes almost no difference in noise level. I have a speed control but it stays very noisy down to about 2k? RPM which...

I am using a porter cable 7310 laminate saw on a homemade gantry table, it works well but is very noisy even free-spinning. Is there any way to quiet these down? they seem to be quite popular so...
