Why not just use a .0625" copper shim?

.....
Now that I've got the RAMPS figured out and see how much it can do in such a small package
I don't see any benefit in trying to use Mach 3 as the control unless I build something that needs nema 23 motors
and my bigger drivers.
Working on a few more pimps for the prusa first though.

Hoss,

For your RAMPS board do you run any heatsinks or fans on the Pololu drivers to cool them? I noticed the Pololu chips get toasty. I have them set to 0.8A for the Ebay steppers and 1.6A for the Z driver due to the parallel motors.

thx

Hi Hoss,

I noticed that you ran your printer from an sd card in one of your videos. Do you need a computer hooked up to tell it to start printing and or do an estop or make another of the same part? Or is there a means of controlling the printer without a computer?

Thanks

Well got the Prusa Friday and have it moving today. So cool for a newb. Anybody using Gen 6 board to control heat bed? My directions just wire direct and electrronics are a challenge for me.

Anybody seen a Gen 6 board capable of 2 extruders like Hoss's?

The kit I got from Ultimachine came with little heat sinks for the pololus, I have a little fan blowing across them too just in case.

there are a couple interfaces on thingiverse I may look into for true standalone but my little mini laptop finally has a use running the printer.
I'd feel bad tossing it aside again.
I still can load a program on the sdcard and hit print on the laptop then it's free to work on CAD or slicing etc. and not tax the cpu.
theres a reset button on the ramps that can stop the printer when it's running off the card by itself.

This is the hot end support I made from ally for the 2 j-heads.

Thanks, It's a curse sometimes, some people just don't like you because you are popular.
They still check out the threads all the time for what's going on and that adds to it. :wave:
Oh look there's a couple down there right now.

Congrats!
I don't know much about the Gen6 but does it have room for 5 drivers?

My Gen6 board only has 4 drivers and no connection for heated bed. I think I have a v1(batch 1) board though. I think the new Gen6 deluxe(batch 5) has added heated bed and cooling fan connector. Can't you run the z steppers in parallel off of one driver? I thought I saw that somewhere.

[LeeWay]

Correct on the Z motors. If you got the Gen 6 from Makerfarm, it came with a splice cable for Z to run them off one driver. I turn the pot up on that one a little. No need to go all the way, just hit the sweet sounding spot and you are good.

Mine doesn't have a version number on the board itself. It was ordered in Feb.

If it did have an extra driver, I don't know what software it would use then. Mine uses Pronterface, Sprinter and I use Slic3r.
Not yet familiar with anything else other than Mach 3. Still waiting on guys to get the extruder temp and heat bed configurations in it and then I might make a swap.

I was told that the heat bed without a temp control would only get to 110C. Not so. Mne was almost 160 C when I checked the other day. Way too hot even for ABS. Consider ordering an MK138 kit to control the bed temp manually.

I didn't realize when I bought the Gen 6 that it didn't control the bed temp as well as Extruder temp. Not enough research on my part.

I like ya because you have this folksy almost "Santa" in his workshop quality to your video's.

Yeah the Z on mine runs 2 motors but you still need 5 drivers, X, Y Z and the 2 extruders.

Forgot the second extruder. One is enough for me currently. 2 would confuse me even more.

Are you planning on updating your website with 3d printer information like you have done with the mills? Your videos will get a lot of people into 3d printing that may have not considered it before.

My buddy and I have are thinking that if we were to get a couple of these printers it would give us the ability to practice 3d drawing as it's making parts quicker and cheaper then using the mill. A lot of the same concepts that we can learn will only help us get better on the mill.

[hoss2006]

I started working on a page on the site, I'll add more as time allows, probably during those long prints.
