I received my motors. I found them on eBay for about 55$ with the shipping for 8 of them. Good deal.
So, I started to work a little more on my Prusa. The Z stage is done but need some adjustment. I think I will look to find another coupler. I don't like the one from the Prusa Plate.
I now need to find Belts, I didn't find anything locally. I was thinking to use some from old printer but after dismantling many printers nothing can be use for that.
Next steps : Z stage adjustment, X carriage, and extruder.
