Re: Solidoodle Belt and Pulley specs / belt replacement guide

Everything is running fine using the original belts for the y-axis and the new belts for the x-axis.

3dcad, EEPROM instructions:

1. http://calculator.josefprusa.cz/

Get a ball park by entering the standard Solidoodle specs:

Motor step angle: 1.8
Driver microstepping: 1/16 uStep
Belt presets: MXL belts (2.03mm)
Belt pitch: 2.03mm
Pulley tooth count: 18

This will calculate to 87.58 steps per mm. Firmware is factory set to 88 steps per mm.

2. Change values in calculator to suit new belts and pulleys:

Motor step angle: 1.8
Driver microstepping: 1/16 uStep
Belt presets: GT2 belts (2.00mm)
Belt pitch: 2.00mm
Pulley tooth count: 20 (may be different for you depending on which pulleys you buy)

Calculates to 80 steps per mm. This is the value for the EEPROM settings.

3. Open Repetier-Host and connect.

Go to Config > Firmware EEPROM configuration

Change value from 88.00 to 80.00 for X and Y (depending on what belts you changed) on the top row.

Click Save to EEPROM and then yes.

Finished!

Print something round to see if it comes out as a circle or oval.

Re: Solidoodle Belt and Pulley specs / belt replacement guide

It's worse, the rod is 6mm which means the bushings have a 6mm bore, but the holes in the frame that the bushings are mounted in are 1/2".  Maybe you should get a 5mm rod, some 5x13mm flange bearings, and ground the holes out from 12.6mm to 13mm.

I didn't replace that little belt. As yet unable to find a local supplier...

Re: Solidoodle Belt and Pulley specs / belt replacement guide

So far my prints look exactly the same. Not sure if this mod is worth the effort and particularly the stuffing around with the rear 1/4 inch rod.

Re: Solidoodle Belt and Pulley specs / belt replacement guide

I will hold off on my order then. It looks like it will be nearly $100 worth of hardware unless I start scouring ebay.

in case you were wanting something for references and you don't have your machine. Here is that mock up

Not to bring up an old thread but IS this an accurate mockup of a sD3?

I just checked out your site for more info. Funny I just got back from Thailand!

I have had good luck with the belts form here:

Might even have the right pulleys.

Those prices seem great! How's the shipping? I may have to look into a belt upgrade.

Re: Solidoodle Belt and Pulley specs / belt replacement guide

Shipping is expensive, but worth it often. If you have a light enough order (<500g) and can afford the wait, you can request chinapost mail instead of fedex.

They're quiet and awkward to order from, but I've had both packages I order (a $40 order and a $120 order) arrive safely and relatively quickly.
