I think it would not be hard to just add two more motor drivers to the system and I have a newer BOB that supports 6 axis. It may be just as cost effective to buy a new 6 axis controller, but I am...

Hi, I am not sure of the stepper motor rating on the shorter one but it came off of an actuator and I figured it would be enough torque for the use. It was one I had on hand and I can easily change...

Hello,
I made some more progress with the B-C head assembly today and I came in feeling pretty good about the way it all went together so far. I got the head assembled to the carriage and the...

Hello, I did more work with this build in the past week but forgot to update here. I completely disassembled the head in order to remove the tall stepper and replace it with s shorter one. It was...

Hello,
I did some more work with this build today. I got the boss mounted to the router mounting base as well as to mount the router to the horizontal rotation shaft. It is not to a state where I...

I got the trim router mount fabricated and together but it still needs the hole and boss for the axis shaft. Just have a couple of pics of the trim router mounted to the plate with the .375"...

I had thought about the axis not being in alignment but to just test the mechanism I am trying to use, I assumed I would be able to include an offset as jsheerin mentioned. I do not have enough...

Thanks Liam, I am trying to keep motivated and it helps to see the encouragement! This is kind of a prototype build or maybe trial and error is a better title, so it could be kind of empty if the...

]I got more done with this build today and got the B-C head drive mechanism assembled and lined up inside the housing as well as to mount the motor to the rear side of the housing. I have been...

Hello, so it is way past 2015 and I am just now trying to get back into this B-C head design and construction. I kind of lost my way and although I have the parts that were made and the drawings it...

Hello, I admire your tenacity to go ahead with the Gingery build lathe with HRS and I have built the lathe, the milling machine and the shaper but here in the USA cold rolled steel is readily...

Thanks for all the help to get the Mechatronics 4 axis board working with this 3D printer build. I was able to get all the axis working but could not figure out the breakout board section to drive...

I have done some upgrades to this machine since the last post here and the high speed water cooled spindle is the most significant. It is such a great improvement over the trim sized router I was...

Rich,
Thanks for taking the time to help. I went back through all the settings and found outputs enabled that were not needed and after disabling them and restarting Mach
the Y axis is working...

Rich,
Thanks for posting the link to the Mach config. PDF! I figured I might as well read through it all again and I seem to have found my configuration blunder. I use this same laptop for running...

Hello,
I got a 24V power supply installed and everything wired but I can not get the motors to turn! They are powered and the motors stall but I can't get them to move.
I used the pin settings as...

Thanks very much for posting the .pdf for the Mechatronics 4 axis board!

Keep the taps well lubed and you should not have to retract until the depth has been reached. Use a good tapping fluid and keep the taps lubed and I do not think you will have any problems. The...

Hello John,
I appreciate your efforts to help me. Thanks!

Hi Ian, and thanks for the kind remarks!
Today I got a picture of the left half of the sacrificial plates with 1/4-20 threaded inserts installed in a grid pattern every 4.5" apart for ease of...

OK, today I got a picture of the Mechatronics Bipolar 4 axis board.

Hello John.
Thanks for your help and detailed information! I will try and get pictures later today and post them. The help is greatly appreciated!!!

So apparently no one can help with how to configure and the setup of the Mechatronics 4 axis controller board. I guess I will move forward and remove this controller from my 3D printer build and...

I don't have any experience with the Cleveland taps, but with Balax you can expect as much or more than rcs60 has stated as long as the aluminum is clean(no abrasive dust in the holes. You can also...

If you decide to go with manual tapping I would recommend using a Procunier tapping head over the Tapmatic and check out the Balax roll taps which do not produce chips and the thread is roll formed...

Hello,
After some searching I have been unable to find links to any documentation for the Mechatronics 4axis bipolar board controller. I thought it would be worth a try to see if someone might have...

Yes the second one looks better than the first. As long as you let the mold cool down it will probably be OK, but if you are not pushing to get it done right away letting it set overnight will not...

I got my Petrobond from a foundry supply in Oakland, CA because I lived in the east S.F. bay area at the time. You should be able to find a source near you with a search and it has been years since...

Another thing that helped a lot with molding and casting is Petrobond molding sand. It is an oil base sand and is very fine. It allows me to mold any time without tempering the sand and the main...

Yeah, I have the MultiMachine plans and was impressed with the capacity that could be gained by using the engine block but I have not done anything with the plans other than look through them. I was...
