Re: Is there a list of recommended spare parts?

I destroyed my teflon tube while learning how to deal with PLA... ultimately I installed a cold end fan and no longer ruin my teflon tubes. I ordered a small roll of the teflon tube at a better price from eBay since it can also be used to make a bowden extruder for faster printing. for PLA printing ...

Re: Temp measurement

Thermocouple display + sensor, $5 shipped

I use these for engine tuning and they're very reliable.

Not as accurate as a thermistor with a narrower range but good enough for our purposes.

Hey I'm an H1 user from Montreal.

I recommend RAMPS it's much easier. You can get cheap RAMPS kits from www.reprapdiscount.com

Re: 4 Axis Board - TB6560

single motor z axis gives you the advantage of being able to manually jog both sides at the same time at the start of the print, I do this all the time to get my first layer height just right. you should wire the motors in series like they do on the reprap RAMPS setups. The z-axis doesn't need much ...

you can coat the resistors in ultra copper so that it displaces any air inside the holes, silicone is more thermally conductive than air.

Re: I just turned my H-1 into a $2k machine!

Your exhaust fan is too big, you're probably cooling down your chamber way more than you need. The commercial printers use around 35c chamber temperature.

Re: which steppers come with the RAMPS kit?

Your logic is spot on, my point is that these high torque steppers cost a few bucks more, and you can take advantage of that torque with the parallel port driver as it goes up to and above 2.5A, but on RAMPS the motors work at a reduced capacity. I believe the max of the RAMPS config is about 2A, so...

Re: which steppers come with the RAMPS kit?

From what I'm reading, RAMPS functions better with a motor in the 1-2A range, and cannot fully power the 2.5A motors. The motors run nice and cool because of this, and the stepper drivers run very hot because they have to be set pretty high to drive the 2.5A motors. Seems like the 42BYGHW609 would b...
