How large a stepper will this drive run?

[PlasmaGuy]

Enclosed is the link for the driver I am using.

http://www.microkinetics.com/mtdrspec.htm

The motors I currently use are too small and I would like to step up to a larger motor. 5 x 10 table

When emailing Microkinetics I get no response and phone calls are a waste of time too.

I would like to go with Tom Caudles system but the economy in North-Carolina is slow.

So what 1.2A/phase allow me to run? Operating voltage of 40VDC

Thanks to all,

Tom

I feel for you if you are running a Microkinetics system! I started out with the DM4050(?) drives and their (lame) MicroScribe card & engraving software. The sad part is that was back in 1999 and they still have the same basic technology today. The customer support was not only poor but abusive! Two best days of my CNC life was the day I bought it and the day I sold it!

Which drives of theirs do you have? You can't get much bigger motors if 1.2 A is all they will handle (the drives) but mine would handle 5A and 40 volts (but not high speed pulse rates)

You might want to look at some of our new stuff (MP3000) since it's modular you can buy it along the way. The DTHC module can be added at any time so you can add full Digital Torch Height Control when your budget allows it. The MP3000 Basic is the front end for just about any downstream modern drives. It will plug directly into a G540 Gecko or any of our EZplug Interface cards. You can get some really nice hi torque 23 frame motors (620 oz-in) from www.HomeShopCNC.com that match up to the G540 perfectly. We have the possible Frontend-backend combinations on our website opening page.

The 4 axis Gecko540 is a complete motor drive package. You can add a 48V 10 or 12 A (www.MPJA.com) supply to handle the bigger 600 oz in motors. It has a breakout and I/O but it does not support the new TDM (port expansion) technology we use so you run out of Inputs for doing any Expansion like the DTHC. Our MP3000 interfaces via the external MTA100 using one standard DB25 cable to the G540 and becomes the I/O for the system.

I know money is tight and we have worked to get the price down on plasma cutting electronics.

So if you can budget about $850.00 you could end up with a whole new stepper drive system, motors, and MP3000 Basic, or about $1200.00 with a DTHC.

You won't believe the difference you will see with the new drives and motors!

Tom,

You aren't kidding about this company. Honestly, I don't know how they have remained in business? No one returns calls or emails.

I looked into up-sizing the motors years ago before the forum had even be born and I think now that the drive was maxed out.

You might be hearing from me sooner that expected

Thank you for you quick reply

I bought toms plasma pak 3 when I built my 5x12 table. it was well worth the money. Toms support is awesome too....
