Re: DRV8825 tiny trouble - 7 years ago
QuoteNoobMan The default 500mm/sec means 30.000mm/min, which is way too fast, especially for cartesian machine. A more practical range would be around 70-80mm/sec for max speed. But you can test to see how it behaves at increasing speeds, then you find your own setting for the max speed of the machine. Also later on (if and when) you will test printing, can basically do the same thing with the spby RickK3DNOB - Controllers
Hot End Temp - 7 years ago
Hello All Heating up the J - Type Hot End to 185 and I noticed this curve on the graph (See Attachment). Is normal for it to do this, the overheat and then drop temp and over heat.

I will have to say that when you mentioned in your post about laser cut parts, you were spot on. I routed 6mm plywood on the original I3 frame to find it was out of square by .02 inch. So I bite the bullet and get it CNC'd. As far aby RickK3DNOB - Prusa i3 and variants
DIY Prusa I3 Rework from Scratch - 7 years ago
Hello all, Thanks to everyone that has posted in this form. I have learned a lot. I am attempting to build my first 3D printer based on the Prusa I3 Rework and have some questions for everyone here. I currently live in Central AB, Canada. In the middle of Edmonton and Calgary so kinda in the center of a black hole when it comes to shipping stuff for cheap. I have decided to source as much as I caby RickK3DNOB - Prusa i3 and variants
