Very Pleased
I purchased the kit on Saturday and it arrived in VA, USA on Wednesday. Spent 3 hours putting it together and tried the calibration but got random clicking from the motors. Found out that in the rush of putting it together I has swapped the Z and Y axis endpoint switches. Quickly sorted that out and performed the calibration. Used the built in PRUSA logo as a start, but it had failed when it started the actual lettering. I had intentionally left out the set screw for the extruder motor guide because it was hitting the plastic that guides the filament into the extruder. This worked for the base layers but started slipping when it got time for the letters. I sanded some of the set screw down and trimmed a little off the plastic so it wouldn't hit and voila it was good to go. I printed the PRUSA logo a second time and it worked flawlessly. All in all it was about 4~5 hours from opening the box to a #D printed part. I am very pleased so far.
I did have a quick question though, when preheating I moved the z axis through the LCD menu and the extruder's temp started rising dramatically until it hit the max temp err. I has only done this once. Any ideas?

Hi Jarred and welcome to the forum.
Firstly the set (grub) screw should not hit anything; personally I would check the assembly. Make sure the drive gear is the right way around and that the screw is tightened down onto the flat of the motor spindle.
With regard to the MAX_TEMP error, there is nothing you can do from the menu that would cause this to happen. I would think that this is most likely a "one-off" event that does occur with operating systems in general. I would suggest that you keep an eye on it and if it happens again, note down the circumstances and anything else you were doing with the printer and let us know.

Re: Very Pleased
Thanks for the reply. I will keep an eye out for any drastic rises in temp. I will submit a photo of that extractor motor gear when I get home. It's printing a scissor jack that I got off the internet. Figured because it was single print mechanical model it would be a good test of my calibration heights.
Re: Very Pleased
Yeah, it's always a good idea to start off with a really complex model... 😉
There's more to calibration than getting the nozzle gar right. For this type of object, the flow rate would be much more important, and that requires various other calibration tests.
Have fun with it! And any problems, please let us know.

Re: Very Pleased
You jinxed me ha-ha, the print failed. The middle screw fell over. I printed the vase sample model from the supplied SD card and it came out nice. Except for the layer transition spot on the model. As it raised .2mm for each layer at the same spot, the vase wall was thin. By the time it got to the end of each layer it was the correct thickness. Would slowing the print speed or raising the flow % correct this issue. I don't know the exact setup for the supplied model but maybe it is retracting the filament a little too much during each layer transition. Thank you for help.

All printers have slight differences and are working in different environments with different filaments. The pre-sliced files are prepared with general default settings and will not precisely suit every printer.
Ideally, you will measure the amount of filament fed when you issue a "feed 100mm" instruction and use a slicer's "flow tweak" setting to increase/decrease the feed slightly. All part of the calibrations necessary to get a good quality print.
