Have printed the new end caps/belt holders.  Now, to find enough hardware for the new ones.  Thanks very much for the link!!

Hardware ? Do you mean the extra 3 mm screw/nuts ? They should all companies dealing with small items for hobby use have in stock. The last I bought was in a ordinare hardware store here in Denmark. I'm sure you can also find them at Banggood, Gearbest and Hobby King.

Regards Leif.

He is from Rockford Illinois USA :o

 :-[  Oh, the man getting wet feet if he just has to go around the corner for a good deal.  :'(   

The text under info is still relevant, even if it is going through google translate !!!    :)

Adjusted the current. Doing the same thing, just more exaggerated. Where can I get a new stepper driver?

Maybe here in your "backyard": https://alfa-tech3d.com/da/elektronik/stepper-motor-driver-a4988-with-heatsink.html    ;)

Pse, just read the text under info further down the page.

Thats what I was thinking. Have the bed move in the z direction.
I figure, to raise the machine with some 2020 extruded and install a z axis like the one in the hypercube evolution project liked above. There is also a remix on that design to allow for one motor to control two lead screws (one on each side) for more stability. That and take that "z platform" and just bolt it/marry it somehow to the legs for rigidity. Keep the x/y fixed and move the z up and down

I saw the Bid E but cannot justify the price. I would like something that big, but and A3 would be a perfect size for me.

Now, the largest heated bed I could find was 300x300. I do have a friend with a rather large CNC mill (600x250), so I could probably convince him to route me out a PCB heated bed. After all, thats the type of heated bed he made for his custom built 3d printer.

40x40 cm heated bed: http://3deksperten.dk/silicone-heatbed-400x400-mm-220v-560w.html
50x50 cm heated bed: http://3deksperten.dk/silicone-heatbed-500x500-mm-220v-850w.html

The same can be found in China or another low cost country much cheaper.

Thank you for help with the belts.  Yes, my small bolts are sitting flush, so I will try to use longer ones.  Yes, I did break one of the acrylic pieces, but I'm using half of it and the large bolt to hold down the belt.  Seems to be secure, but I would like to 3D print one if i could find a .stl file for it.

Hi, first post here.

Can not imagine it's a belt problem you have, but a problem that your drivers for the stepper motors do not deliver enough voltage/power. There is a small trimmer on each of the drivers that controls how much power/power each shaft's stepper motor receives.  http://wiki.eleksmaker.com/doku.php?id=eleksmana  Usually you get given a voltage can be measured at the driver but here you need to set haphazardly pious. Maybe another person here on the forum knows how the power is measured, I'm missing the measurement to so my stepper motors do not jump any step over ???

Regards Leif.
