my motionking stepper (23HM6403) is rated: 2.5A

page 1, max current is 2.5A per axis
page 4, vref is 2*desired current

so 5v isn't a crazy value for me, unless I miss something. But I could be mistaken

Teach me to try to answer something half asleep.

You are correct,

The manual says that to have 1.8a you would adjust the V-ref to 3.6 VDC on your voltmeter. I know I remember somewhere back in this or one of the other phlat threads that hector ( easy-cnc ) said not to exceed the 1.8a setting as it could damage the board if not the motors.

In my case, I have them set for 2.5 vdc on each axes and they seem to be running fine. That is very close to the setting ( arrow on V-ref set to stright up and pointing at the chips ) Mark called for in the setup video.
When I was adjusting them, you really had to bearly move the v-ref to get a major jump in volts. Took a few mins to get it dailed in.

That I can't answer as I can no long see those labels to look. Still, it does not "sound" like thats correct because setting the V-ref to what mark called for will give you 2.5vdc on a voltmeter.

A few people have also burned up their motors, but with no conclusion as to why. The problem is there is no data sheet on the orginal motor. But having recently researched a few replacements, I wouldn't be surprised if this motor can't take more than 1 amp. For one thing the resistance seems high at 10 ohms. Also, from this post easy-cnc says max is 1.6V Vref, which means 0.8A max:

Here is a pic of the label:

I see what you are saying and it would appear that you are correct about the settings on the motors. I know on mine they have been set to 2.5 vdc since day one and they do not even get very warm. Either the motors or the heat sinks.

It may be that I got lucky or for whatever reason my motors are happy at that setting.

In any case, it has been my understanding that anyone that has been having problems seems to have had them addressed promptly by Mark. I know he did when I had my board problem.

Thanks Tony. We do try to offer the best customer service that we can.

Ok, the wife won't let my get my own Phlatprinter, something about forgetting an anniversary...so:

I am looking for somebody who can cut me some foam for a few models, specifically the Dash-8 Q400 and Isreali Kfir or Mirage III....any takers?

Just ordered my Phlat-Premium kit! Cant wait!

Also, I will be using all differint size sheets of foam with mine. What do I need to do on the computer to set what size sheet I am using at the time?

The Phlatprinter sketchup plugin makes that real simple. Also check out the phlatforum, lot of great info and peeps

Nice to see this thread get a bump. Still using the Iron Phlatprinter and have cut around a thousand kits since its start up.

I am looking to talk to some phlat printer owners about a part I want to make. http://www.rcgroups.com/forums/showthread.php?t=1838376

How about posting some pictures of your machine and kits?
