I was just thinking to myself "there has to be someone as crazy as me who would build a 4th/5th with harmonic drives" but all I would find were hobby rigs, not real precision like this... GREAT WORK! Now I'm tempted to get a build going! And you also uploaded the Fusion file for everyone to use! This would fit perfectly on my Sharp VMC. Thanks man.
Ist es möglich mit dir bezüglich dem Anschluss des Harmonic Drive an den Kollmorgen in Kontakt zu treten? Ich hätte die Möglichkeit einen FHA25c zu bekommen. Stand jetzt bekomm ich das ganze zwar mechanisch aufgebaut, aber elektrisch scheitert es. Vielleicht kann man auf den von dir gemachten Erfahrungen und Anschlussplänen aufbauen. If you speak only English I will write the text again if you want. Kind regards
Checkout the recent comments on the video th-cam.com/video/MC0EnJ4XK2M/w-d-xo.html about the same topic. May you guys can partner together, and ask questions that if I am able to fairly easily help with, I certainly will.
Hello buddy. I have a Linux CNC powered machine, with EasyServo Leadshine steppers, and I want to build this. would you be so kind to share post processor. I think this is awesome what you did, and I admire you for that. Beautiful work brother Cheers, Marko
The only kollmorgen I have are the servo drives, no motors, they are S600 603. The harmonic drive FHA-C 32 has 100 reduction, A axis. The FHA-C 25 has 50 reduction, C axis.
I am building a very similar trunion with support on both ends. I already have the a axis 45 size harmonic drive capable of 12.5 rpm what rpm drive would you recommend for the b axis. Would 23.5 rpm be good or do you recommend faster?
I guess torque is more important than rpm for a 4/5 axis. Ideally the faster with more torque the better. But it’s never going to be fast enough for turn type of work.
I simply put multiple g33.1 commands at different depths, so g33.1 z-5 k0.7 followed by g33.1 z-8 k0.8, etc. not sure this will work on all machines, I think it will depend on the encoder on the spindle. Just try it using a test workpiece and a tap you don’t mind breaking :-)
Excellent my friend. I’m not sure of the end mill you’re using for that steel plate but you may want to try these. Company called CGS TOOLS MAKES A 7 flute for. Around $35usd .5dia 1.00 LOC 3.0OAL and it will cut faster, smoother, and overall it looks like they cut a little better than what you have in the video. I’ve taken .250 deep cuts at 200ipm and 4800rpm and it didn’t leave any fracture lines grooving a block of 8620. This is on my pm833t. Cuts that block like butter. Found the end mills on eBay. The 5 and 6 flutes are good too but the 7 flutes are like Cookie Monster on steel.
Thanks Glenn, have been wanting to build the 4/5 axis for a while. It’s cast iron not steel, but to be honest beyond the end mill, speeds and feeds are still a bit hit and miss for me ... recently started using the FS wizard more often and it does helped.

Hi Max. Seeing this comment, you may wish to take a look at a 5th axis that I've just finished. th-cam.com/video/nbxcX9q7XLs/w-d-xo.html
Thank you for sharing.
This is very exciting.
Wow! Can't wait to see the next video
good work. thanks for sharing

Thanks. Sure, see this post on LinuxCNC forum forum.linuxcnc.org/10-advanced-configuration/31813-tcp-5-axis-kinematics-x?start=150#143582
Hi ; what model and make are the motors?
They are Harmonic Drive FHA-C. One is size 32 and the other size 25.
Hi; and the köllmorge. Motors¿ thank you for your prompt answer, also please share reduction ratio..
The only kollmorgen I have are the servo drives, no motors, they are S600 603. The harmonic drive FHA-C 32 has 100 reduction, A axis. The FHA-C 25 has 50 reduction, C axis.
P. Lopes thank you ¡ did not realise that the servomotors come with the harmonic drive in that model
@@PWLopes9000 Dang how much did those cost 😵

how does woodpecker thread?could you teach me in linux since I thank you
