I don't print in ABS, but try printathing.com. You should find pretty reasonable prices there and I'm sure there is someone who will print in ABS.by bethebeer - Job Shop: I need stuff made!
Good to know. Thanks for the fast response.by bethebeer - Repetier
has this been resolved?by bethebeer - Repetier
awesome. Thanks a bunch, glad I misread that.by bethebeer - Controllers
That link is where to get them, or on eBay? Also, the new Rambo board puts a 100k ohm resistor between the ROSC pin and the ground; this is what the wiki schematic looked like to me. I just want to make sure that it would be worth shorting that out. Why would there be such a large resistor there?by bethebeer - Controllers
from new york or from thailand "would be badly mismatched with the 100k trimpot": yea, didn't think that one through.by bethebeer - Controllers
@droftarts: i have never used stepsticks. I have been using pololus with r4 shorted. I just replaced the resistor with a strand of wire from 7 strand 24AWG. They have been working great and supply enough power. I have the 0.1ohm resistors, but never bothered to put them on because everything has been working. I'm also scared to do it because I just have a soldering iron and no good way to woby bethebeer - Controllers
@nophead I shorted R4 on all of my drivers because I had very low resistance motors and it helped a lot. Is there a time when shorting R4 will have a negative impact? What would the negative affects be?by bethebeer - Controllers
Repetier says he is working on an awesome solution. The host does take too much ram. Pronterface does not really run until you get rid of all of the rendering of the g-code. Either way, I am set up with pronterface and eagerly await the repetier for pi.by bethebeer - General
I am going to post an issue on github asking for a release that removes all of the heavy processes, because I think that will not work on the pi, or at least it will slow it down way too much.by bethebeer - General
I am about to set up my raspberry pi as the host for my printer. I was wondering if it is possible to run Repetier-Host. I know that Pronterface has been successfully run on a pi, but I don't know how much processing power each host takes. Please advise. Or i'm just gonna go for it and risk explosions.by bethebeer - General
For me it's 46,856 bytes. I tried this workaround, That got the motors working, but thermistors and heaters are completely dead. Even when I don't used the thermistors I cannot turn the heaters on, but the fan does turn on, using the 7 switch and DIO14. I've seen people have it working by setting the brownout fuse to 2.7V. I have not seen a report of the workaround in the above link to work foby bethebeer - Firmware - experimental, borrowed, and future
Traumflug answering some of my questions again. I am using a gen7 V1.3.1 board with the temp sensor hack described here Also, I am using the SevenSwitch to control a fan. I cannot get Marlin to work. I got it to upload, but Pronterface continually reports a brown out reset. Brown out means, 5V supply goes below 4.3V. That's surprising, as the firmware has no direct influence on this.

Should have posted this here... I am trying to add auto bed leveling to Teacup: I first saw this on nophead's blog(hydraraptor), but, currently, there are several other people doing this.

And is it necessary to use the same power source for all disk power connections? No. You can use a different PSU for each connector, as long as each of the PSUs has a GND connection. The disk power connector's two center pins are GND, typically a black wire. If I used a second power source would I have to connect the green(psu on) wires together and also the ground to allow the board to controlby bethebeer - General

I was going to purchase this kysan motor for my Wade's extruder and it is pretty cheap, so is there any reason not to get 3 more of the same kind for the axes? Maybe to save energy I could get 3 of these motors . Is there an optimal rating for voltage, current, resistance, inductance(how does this affect anything?), or is it steps and holding torque that matter most? I'm going to be using poloby bethebeer - General
Thanks a bunch, I think I will try to throw that together.by bethebeer - Controllers
The stepstick is more sensitive to noise? or the pololu? I am trying to decide which drivers to go for. If I got the stepstick board, couldn't I just put on .05 ohm sense resisitors in place of the .2 ohm sense resisitors?by bethebeer - Controllers
Scratch that last question about the breadboard, but I still can't figure out if a stepper driver can replace an extruder controller, or if both are needed to drive a stepper motor for an extruder.by bethebeer - General
Thanks for the fast responses. There was an Arduino Breakout Shield made for the Darwin: reprap wiki Couldn't(if I had to) I just use a breadboard for all the connections? And can the stepper driver for the extruder hook directly into the motherboard, or does it need to connect to a controller which connects to the motherboard?by bethebeer - General
I am building my first printer using an Arduino UNO and have installed the Teacup firmware successfully. I was wondering if I could use a stepper driver for the extruder without an extruder controller; if not, why not? For the stepper drivers controlling the 3 axes, are all stepper drivers compatible?
