Am I allowed to say that I have a 3D printer I would be willing to swap for steppers or any other parts I need. It is a 4 year old - never used or completed the build.
Hey there Mark,
Here is a link to the Google Drive folder for my project:
https://drive.google.com/folderview?id=1-NlAQWnQT9-zR6cHg8TlpPaHQktba3oB
You will need to request access when you reach my folder. It contains all the STLs for the printed parts and DXFs for the flat parts.
I am sure that Ryan offers a board for the Lowrider. You would probably need to use pass through chips in the driver sockets to drive the NEMA steppers. I opted to use a board designed by Bart During specifically for Ryan’s machines. There are certainly cheaper options available than the one I use.
You’re a '66 model? That’s not old. I’m a '61 model and still young. I am living in Arizona now and loving it. But I was a Tennessean until 5 years ago. Another southern boy.
Looking forward to following your build.
Tom
I am actually a 1964 guy. I used the username for my muscle car I have restored. I have a 1966 442 Oldsmobile.
I also live in a little town in the middle of nowhere GA called Buchanan. We just moved from the Atlanta metro area about a year ago and live it out here.
Hey Tom
I just came across some NEMA steppers with individual drivers. Is this something that I will need for my lowrider2 build. I am following your lead on this. Here is description of steppers
Insulation Class B. Nema23 1.3N.m Stepper Motor Hybrid Servo Drive Kit. 1 x Stepper Motor. 1 x Stepper Driver. Suitable for condition of short-
Many thanks
Those steppers have a little less torque than the ones I am using but your steppers are hybrid servos. You shouldn’t have to worry about skipping steps under reasonable loads.
Have you decided on the controller for your machine yet? Are you using 5 hybrids on your machine?
What do you suggest for the stepper and the controller. I have not even began to look at controllers. If the truth be told I am not sure the function of the stepper driver and the controller and the stepper.
What stepper are you using? Like I say, I want to do this right the first time and it looks like you have worked out the bugs and have the machine I am looking to build.
Peace
Mark
For clarification I understand what the controller, steppers and driver all do as an individual part but
not as they collaborate on the CNC build.
There are pictures of my electronics at the beginning of this thread. I am using the following board to control my machine with GRBL:
I am not connecting the board directly to my stepper motors. I am connecting to external stepper drivers which connect to the stepper motors, much like the arrangement of your hybrid servos. I am using 5 of the following adapters on my board:
Without knowing more about your servo kits I don’t if they need the same signals (ENA, PUL, DIR) as my external drivers.
I recently upgraded to a 2.2kw spindle with inverter. I am currently controlling the speed manually from the inverter because my controller can’t. So…time for an upgrade:
I will need the 5 adapters I mentioned previously:
I will need 2 4-input modules:
To control the spindle speed I am going to use a RS485 module:
This is great. I want to also go with spindle.
I have started to order parts already. Once they all come in I will begin
I got a nice surprise at lunch time yesterday: my boss told me to knock off for the rest of the day. So I quickly designed an upper cabinet in Fusion 360 and sent the gcode to the SD card in my Lowrider. I started the run and it finished just before my nephew and his wife arrived.
The turkey, mashed potatoes, gravy, green bean casserole and cranberry sauce were great! I couldn’t eat another byte right now. So I decided to have something else for dessert…
Happy Thanksgiving!
What spindle are you using. What is the oz on your Nema 23?
Thabks
NEMA 23 - 269 oz in 2.8A
Stepper driver - DM542S
Spindle - STEPPERONLINE 2.2kW
Water or air cooled? Do I also need the inverter. I thought they would cost more. They are the same price as DeWalt 611. Of course the cable is added. I too want to control the speed.
My spindle is air cooled. I just didn’t want to deal with the water lines and pump. I think the water cooled spindles might be easier to find. My VFD is 110V. If I had it to do over I might choose the 220V VFD. My VFD offers three options for speed control: 5V PWM, 0 to 10V and RS485.
What about this 12Nm Nema 34 Closed Loop Stepper Motor 1712.oz.in Servo Driver +60V Power Supply - is it too much? Does it matter? I can purchase this setup for half the cost of a 23.
Would using a 220 V mean I would need a special plug?
