Mach4 General Discussion / VFD wiring with MB3 and ESS

« on: June 07, 2021, 07:53:43 PM »

Hi everybody,

I'm wondering if I can get some help from somebody who might have a similar setup.

For the past year I have been slowly putting together my CNC and with the help from all the forums including this one, I was able to actually put this thing together. So far everything is working amazingly well. I can load up a program and cut a piece of wood (that's all I have tried so far just cutting hardwood and lumber no aluminum)

The way I have this thing working is, I will turn on the spindle manually on the VFD and then go to my computer and start the program. All of that is working with no issues.

What I would like to try to do is wire the VFD to my MB3 board and use Mach 4 to control spindle coming ON at the beginning of the program and turning OFF on the end of the program. I have tried to find some information online but the few things that I have found I did not quite understand, or the person had a different controller board then I have.

I am wondering if there's anybody here that has a similar setup to mine and can share how exactly they wired their MB3 to a VFD and what settings did they use in Mach4 to have this thing working correctly. I see on my MB3 manual where I must wire the VFD but I am not sure what terminal on my VFD I have to use, and other than enabling Mach4 settings what else must be done to have this thing working properly. If there's anybody that can give me a help with wiring this thing correctly it would be greatly appreciated.

General Mach Discussion / controller box questions MACH4 ESS/MB3 Servos CPM-SDSK-3421S and first cut video

« on: January 16, 2021, 08:14:40 PM »

Hi everybody,

I am making progress on my DIY CNC, I have everything hooked up and it seems to be running well. I have actually made my first cut in three-quarter plywood. My feeds and speeds are off but nevertheless, I didn't break anything.

Now I wanted to finish building my electronics cabinet and make everything somewhat organized, but I am struggling with finding the right components to finish everything. I am not familiar with the terminology that those who have experience know about.

If you look at the attached picture you will see where I'm at currently so here are my questions:

I live in the USA, I will be running 220 electrics to the box. What kind of the main switch should I put on here? I see some people use Rotary switches like this one.

https://www.amazon.com/VictorsHome-Changeover-Positions-Terminals-Universal/dp/B07MZ756R2/ref=pd_sbs_7?pd_rd_w=WoyiN&pf_rd_p=de2765fe-65e5-4a88-aaad-a915dea49c67&pf_rd_r=3RB03C1HW1RCQAKD508A&pd_rd_r=63315de4-b7f6-40df-ba13-071ccc7095b4&pd_rd_wg=CV2Bj&pd_rd_i=B07MZ756R2&psc=1

 
I bought one of these, but I think I bought the wrong thing because the switch end up being a transfer switch not ON/OFF switch

Should I have any kind of fuses where the main power is coming into the box?

Should there be a fuse between the power supply and servomotors in case the power supply dies wouldn't want anything happening to those servomotors?

What about the VFD I read on forums that I should have a power line filter like this one.

Any other suggestion anybody might have would be greatly appreciated.

Mach4 General Discussion / New DIY CNC with MACH4 ESS/MB3 and clearpath servo

« on: November 07, 2020, 11:25:04 PM »

I am slowly inching forward in building my first cnc.

I'm using ESS/MB3 combo with clearpath CPM-SDSK-3421S-RLS motors.

I am almost finished installing hard stops. I have temporarily wired all motors to the board, and tuned all motors with clearpath software. I have also calibrated the distance in motors so one inch in mach4 is 1 inch on the table.

What I would like to do primarily is repeated jobs (G54), so my question is;

How do I set up and wire the limit switches, home switches, and Estop?

I am assuming I need 6 limit switches and 3 homing switches. 2 switches per axis for limit and 1 per axis for home. Should estop be wired directly to the MB3 board or wired with limit switches?
How do I wire HLFB + and - from motors for homing?

I was going to use these switches for limit and homing, Is this ok?

https://www.amazon.com/ME-8108-Adjustable-Roller-arduino-Switch/dp/B07D48YKL4/ref=sr_1_36?dchild=1&fst=as%3Aoff&qid=1604807485&refinements=p_72%3A1248921011&rnid=1248919011&s=industrial&sr=1-36&th=1

What is the best way to go about this? Electronics and electrical schematic is not my thing so I'm struggling reading and understanding ESS and MB3 manuals

A short video of machine working.

Appreciate any help I can get to get this going!

General Mach Discussion / DIY CNC with ClearPath Servos

« on: October 07, 2020, 06:51:46 PM »

Hi Everybody,

Looking for some help with wiring the Clearpath servos. I am building my first DIY CNC and I am struggling with the correct wiring. I'm not good at reading and understanding schematics (I am a woodworker) so if somebody can explain this to me like I'm a 5-year-old.

I have Ethernet Smooth Stepper (ESS) attached to the MB3 board and I have a 1000v toroidal power supply

https://www.antekinc.com/ps-10n80-1000w-80v-power-supply/

I need to use 4 motors, Z, Y, Y, X. Two Y motors should be running parallel with each other. The MB3 board has 4 connections for each axes. But Servo motor is showing 8 wires coming out for connection to MB3 and 4 power connections to the power supply.

The Clearpath servo manual is suggesting to wire power to servos in a star formation so I'm assuming each wire going directly from the power supply to each motor. I'm also assuming the RED wire going to "+" and the BLACK wire going to "-" on my power supply.

https://imgur.com/gallery/egK1uR1]https://imgur.com/gallery/egK1uR1]https://imgur.com/gallery/egK1uR1

As far as controlling the motor you can see in the picture that the Z-axis has 4 connections on the MB3 board but the servo motor has 8. How do I connect these 8 wires?

Is there somebody that has a similar setup and can share pictures or drawings of motor connections?
I looked at the manual from ESS and Clearpath and I do not understand it

Thanks

General Mach Discussion / New to DIY cnc , Looking for some guidance and advice on first CNC

« on: March 12, 2020, 08:54:45 PM »

Hello everybody

I am in the research stage of my build and this is what I have so far:

WHAT I WOULD LIKE TO DO RIGHT NOW:

I am looking to build a solid and sturdy MDF-Plywood frame with a 24x48 working area to start and option to machine the vertical edge of the material. In the beginning, I would like to machine hardwoods and some plastic.

So this is what I'm thinking

• 4 CPM-SDSK-2310S-RLN ClearPath Integrated Servo Motor 4 NEMA 23
• 350/500 Watt DC Power Supply Output: 75 VDC - 350W / 500W(fan-cooled) cont; Input: 108-250 VAC
• Y-axis 1500 mm rail and 2010 ball screw with double nut
• Y-axis 1500 mm rail and 2010 ball screw with double nut
• X-axis 1000 mm rail and 2010 ball screw with double nut
• Z-axis 400 mm rail and 1605 ball screw with double nut

• 2 pcs Hiwin rails HG20-400mm with 4pcs HGH20CA bearing blocks
• 2 pcs Hiwin rails HG20-1000mm with 4pcs HGH20CA bearing blocks
• 2 pcs Hiwin rails HG20-1500mm with 4pcs HGH20CA bearing blocks
• I already have a router

The rails and ball screws are Chinese made. (ebay)
(called clearpath customer support and tech I was talking to told me I should not spin the 1500mm 2010 ball screw more than 1800rpm)



WHAT I WOULD LIKE TO DO IN THE NEAR FUTURE:

• Build a super sturdy frame with a combination of aluminum and steel and then transfer all hardware to a new machine.
• Upgrade to a 2.2kw water-cooled spindle
• add MPG
• add rotary
I'm sure there are going to be other things just, can't remember right now.

So this is what I'm not sure about:

So at first, I wanted to go with Acorn board, I really liked their interface and looks like good support, however, only 4 axes, did not want to pair two y-axes together.
My understanding is, with servos, I do not need the drivers, only 5axis BOB

I feel lost here. What 5axis bob should I go with? I'm looking for something that a lot of people use so if I run into the problem I can possibly find the solution from others.

Electronics is not one of the things I know much about, so if you have any suggestions please share.
Forgot to mention, I'm going with the MACH4, it seems like a lot of people are using it.

Thank you very much

Please excuse me, English is my second language
