Amazing build, thanks for showing it in such a detail...!

Neil, I had a search running for years at ebay looking for an harmonic drive at the right price (under $150) big one cost was 70ish small one was 150 but is mint new, both work perfectly. Having...
The info you need is right there in the pdf you posted, printed pages 7 and 9.
Pablo
Thanks!
Yes, of course, the left side needs parts, but I wanted some feedback on the general design before moving forward.

Hi guys, after virtually years of wanting to have a fourth axis on my cnc router I finally got the part I needed the most, a small harmonic drive. It wasn't my first one, but the first one was way...
Hi Peter, found you here after finding at youtube the 4th axis/indexer you made for the haas minimill, I just purchased an harmonic drive for this same purpose. I saw in the coments that you saw the...
Buscando sobre Utilogic llegue a este hilo y veo que me mencionaron :)
Estoy terminando de hacer un completo retrofit de una de estas maquinas, el viernes pasado hice este video de los primeros...
Easy, Haas here in Argentina wants 2200+tax for the drive.
Thats why I ask here and you helped me a lot so far. :)
thanks but he provides no warranty, I purchased an used fanuc power supply in the past and it failed when we installed and got full refund, will look for a seller with better after sale warranty.

Do not repeat your questions! :)
I just replied in the other thread.

Syil has nothing to do with this.
On mach3 go to config>general config and check NO FRO ON QUEUE on the rightmost column. It enables changing feedrate while machining. The change will happen after...
if it moves slow check motor tuning I configure them to around 3 or 4 turns per minute.

Here are some photos of the machine and its tag to clarify things:

Can't find it on ebay, do you still have the link?
Thanks Mike.
Did not looked on the door and the other amplifiers have the same markings, will look on monday, we are currently using the 4th axis as replacement, but we need to use the 4th as...
We have a Haas VF-0 Mill that fails on one axis, here are the photos:

Sent the email but I got a fast reply (Thanks!!) telling me that Rev.2 g250x boards are not compatible with Rev.8 motherboards, so I guess I will have to do the first post design...
Pablo
Purchased all the parts but never build the boards, I just read your post and decided to send an email to Gecko, if the price is right I might go your way too.

Im retrofitting a mill, its about 5 years old, it came with two round nema34 steppers (y and z) and one nema 34 square (x), both types use the same driver, so I assume they are similar. What I want...
Sam, today I was able to remove the motors from the machine and you were right, these are steppers. The obvious confirmation came when I turned the shaft and felt the steps :)
Already deduced the...
upon further reading, maybe these are steppers wired unipolar as you told me, unipolar has less initial torque but the torque curve is flatter, maybe this explains the 4:1 reduction
maybe, but if these are steppers indeed, I wonder why they use a 4:1 reduction, that would be counter productive.
Also, on the square motor, there are two sets of cable of the same color, one...
Hello folks, Im posting looking for help identifying these motors, they are hooked to a small CNC mill, I have absolutely no reference about them, just my educated intuition. I think these are servos...
Neil, Im looking at SX3 schematics and AN1101 pdf, it appears that MC33035 needs a pot with wiper on pin 11 which goes thru a diode directly to pin 4 (E6V) to adjust speed but you suggested to use...
Thanks Neil!
Pablo
Its just a matter of usability, I want to put this motor on a wood bandsaw, to reduce the saw speed from 800meters/min to about 60m/m
I will use it mostly for wood, so it would be simpler to have...
sadly the pull up did not work, any other idea?
Pablo
I think nothing is fried yet, its the pot that does not work, if I connect the buttons everything works OK. Will try the pullup on monday. Thanks!
Pablo
Hi Neil,
Bridged K2-K3, connected the pushbutton board and it worked OK.
Connected a 10K pot as you described and it does not turn.
Your idea was to put a variable voltage on the feedback of...
Thanks for the detailed explanation Neil, one question, when you say chassis, you mean any metallic part of the motor or the heatsink, or both?
Thanks again!
Pablo
