The Sunhokey Prusa i3 uses Marlin 1.1 Before using the SD card, get it printing using an attached PC, to 'break it in'. Once you are happy it's printing correctly, use the SD. I would be happy if my Sunhokey would read the SD they shipped. I just get 'no SD', so while the machine works fine, tethered, I'm buggered with longer printsby ledaero - Printing
Quotegemors Got it loaded, I initially downloaded some file some where that did not compile. Got the marlin file from Geetech and that worked, well it loaded. but I had heaps of issues XYZ only moved in one direction XYZ home did not work XYZ end stops did not work Heatbed was reversed Fixed all those up and now stuck with the last issue. The extruder is feeding in the wrong direction. Any idby ledaero - Prusa i3 and variants
I'm also a fan - it's not 'the best 3d printer in the world', but I paid $315 for it, shipped, with 2 rolls of filament and an 8gb SD card. At that price, there's not much that can touch it. Yes, the acrylic frame is a little fragile (take care of your toys!) Yes, the Merlin iteration they ship with it is a little meh But... the acrylic frame is dead accurate, easy to assemble and you can go fby ledaero - Prusa i3 and variants
Quotegjt211Some things I done on my setup - hopefully to prevent electronic problems in the future. 1. Added a wire from the earth terminal of the power supply to the 12v negative (ground) wire. 6. Changed the stepper drivers to DRV8825 types (don't forget to set the current limit and remove jumpers 1_2 & 3_4 for 1/16th stepping). I set mine to 1.5 Amps. Other things I found...

The cost of the board is so close to that of a smoothie that it's not worth taking the chance for $20. I have already added Bluetooth to the Smoothie, putting an ESP on shouldn't present any problems -and there's no need to modify any firmware, the Smoothie is already set up to use an external UART. It's just a matter of programming the ESP to join your WiFi network. What is needed is a TCP serby ledaero - Controllers
I know this is a bit old, but FWIW, Igus now sell their polymer bushing material as a filament for you to print your own: I am heading towards the reduction of inertia as the way forward in improving print speed and quality and am using carbon-fibre shafts with Igus polymer bushings and finding it is working really well. The overall cost above that of a steel shaft/LM8UU roller bearing is aboby ledaero - General
I have a CNC router, but AFAIK, there isn't a laser cutter in the entire country (I have the first and - so far - only CNC router). Do you think it would cut fine on a router? I have been wanting a Tantalus-style printer for ages...by ledaero - Tantillus
You can make your own linear rail using the parts at Robocutters.co.uk. I've just finished a 1.5m x 2m CNC router using their parts and they are great. He sells wheels, rail, plates, pretty much everything you need to make your own rail - and it is modular and extensible - if you change your mind later, you can repurpose the wheels and plates to some other device.by ledaero - CoreXY Machines

Quotekram242I like the idea. If only they would roll or maybe if they were recirculating. Like you stated, they are just too tight in their current form. QuoteA2Try adding a ring of small ball bearings to the bottom of the bore to allow the main bearing the ability to spin. QuoteEL34yeah, they would have to circulate is what I am thinking. And the balls need to be smaller in order to keeby ledaero - Extruded Aluminum Frames
I buy mine from China. Even factoring the shipping, etc., it's still cheaper than in Europe and definitely cheaper than anything from Misumi. And the quality is really good - very heavy and strong, much more than I thought it was going to be. I paid US$3.50 each for a 1000mm piece.by ledaero - Extruded Aluminum Frames
