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:

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.

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

How about posting some pictures of your machine and kits?

Hey guys. Will this cut through thin pieces of carbon fiber (for quad frames and such)?

Also, does phlatprinter ever run any sales? I have a specific number I won't go above and they are close, but not quite.

Hello L0keman. The Phlatprinter was specially designed to cut sheets of foam. Carbon Fiber is a very hard material and is not an ideal cutting material.
Currently, we are in the process of redesigning the Phlatprinter using V-Slot which is an aluminum extrusion. We are then going to be releasing the Phlatprinter OpenSource so you can pick and choose what materials you want to include in your build. The total cost of the Aluminum Phlatprinter is yet to be determined because the design is not complete. We hope to have this done in time for the indoor cold months that will be upon us before we know it.
Thank you for your interest!

If you or anyone would like to be added to the waiting list, please contact us at phlatboyz@phlatboyz.com.

Thank you,
Mark and Trish Carew
