General Discussion / Stepper Motors & Driver Information

« on: September 02, 2016, 01:24:39 PM »

I have just purchased from you the following -
PMDX-424
PMDX-407
PMDX-179-PAN
I have also bought a 2 year old computer running Windows 10.
I am looking forward to getting everything up and running.
Question about Stepper Motors and Drivers - please see your comments below from a past topic - is the comment true, as long as the stepper motors and drivers are matched, they will work with the boards that I have bought from you?
Yes, this is a gantry machine with 2 motors moving the gantry.
Any direction in this area would be a big help!

Your past comments -
The 425 oz-in motors that you currently have are possibly a little
underpowered for a 4' x 4' router depending on how fast and hard
you need to cut. Hopefully this is a gantry machine with a tandem
setup moving the gantry.

More powerful motors would require upgrading to a NEMA 34 or
to NEMA 23 oversize 60 mm motors which typically have a 3/8"
shaft instead of a 1/4" shaft.

Last question - if you were starting to build a control box from scratch would you buy the PMDX-424AC or PMDX-424DC and briefly your reason.
Thank you for your advise.

Thanks Steve - this is great information that I will hold onto to, but for now I will move forward with your idea of connecting to the Xylotex box - I had planned on opening up the Xylotex box this weekend.
The CNC has been a wonderful project to work on, and I have managed to master all of the problems along the way with all of the great help in the CNC community.

I would like to ask for your recommendations on the equipment I should buy, I would like to buy new drivers and if I have to I can replace the motors as well.

The drivers and motors that I have now seem to work well but I do not have enough knowledge to know the difference.

The motors that I am using on the CNC now are Nema 23 Motors - 40V 4.0A Drive Box with Four 4.0A 425 oz.in.

The equipment that I am thinking about buying from you -
PMDX - 424
PMDX - 407
PMDX - 179-PAN

I would like your recommendations on the motherboard & the Gecko drivers as well.

I am not a electronics expert but I can put parts together and follow plans do you see that this will be doable for my level of skills?

Any help would be greatly appreciated!

I have a home built CNC 5' sq. and working now just fine - for multiple reasons I would like to change from a parallel port using a Xylotex system to a newer computer using a usb and need help to understand what I will need to do this.

Things that I will need the new system to be able to do -
Run 4 motors, 2 slaved together - I understand that the slaving will be done in Mach4.
Limit switches - limits and 3 home switches, touch plate, Emergency Stop.

Things that I would like it to do - spindle on & off - a few more slots to grow with.

Thinking about using - PMDX 416 & PMDX 407.

My basic understanding - I have a computer with Mach4 on it with a USB connector, and using PMDX 416 & PMDX 407 - do I need anything else to connect to the CNC?
Appreciate any help understanding the connection set up.
Thanks
