GT2 2mm Timing Belt retrofit on X and Y Axis

Post by seaton » Tue Aug 06, 2013 5:46 am

When I had some problems with my Y-Axis due to the sagging Z-Axis mount I inadvertently overtightened and broke the wire in my Y-Axis Belt, while still functional, it had a lot of backlash due to the belt stretching on the Y-Axis.

I couldn't find a local source of the M3 Belt thats used on the felix here in Australia,so I went for the GT2 2mm pitch variant with a 16 tooth pulley.

Since replacing both X & Y Axis I'm really pleased with the results. Printing appears much quieter and smoother and I've been able to up my print speeds and have also tuned my acceleration up to 4000mm/sec with no quality or vibration issues.

In theory by using the GT2 belts and pulley combination with the existing stepper motors the X and Y resolution has gone down to 10micron.

I did have to make up a two new belt tensioners for this new belt profile, although left the other ends as is and used a wedge, just in case I want to go back, so far no problems over the last week of printing.

I'll post some photos shortly.

sorry everyone I had uploaded an wrong version of the STL to thingiverse where the belt was too slack fit, on of my earlier versions, I've rectified the situation and the correct version is now on thingiverse.

Just tried printing these, but there doesn't seem to be much space to fit the timing belt.

it's tight but it fits, you can prise them open slightly, I designed it to be a bit snug as the smaller tooth pattern if not snug allows the belt to slip
