Wow that was a fast response, makes me feel guilty for taking so long to respond =-O sorry about that!
I will try to print up some fresh belt tensioners for those problem areas and see if I still have those issues.
I'm not 100% on the issue your having, but if my understanding of your problem is right you can put the tensioner on the other side of the sliding block, the side that doesnt approach the stop, as long as you losen the pulley grubs when you attach it the tension will be around the whole belt and so should make no difference which side of the sliding block its on, unless your running one on either side, which i didnt need to do, so i guess never encountered the problem.
That all applies provided ive not misunderstood the problem!! maybe stick on a picture if that doesnt solve your problem, and ill change the design a bit.
I added four of these to my Ultimaker and ran into the following problems:
- When the head goes all the way back on the y axis, it ends up hitting the belt tensioner on the back sliding block before hitting the stop switch. Its the top piece of wood on the head that's hitting the uppermost piece of plastic on the belt tensioner. I am going to try to resolve it by trimm
ing that piece of plastic off.
- When the head goes all the way right on the x axis, the belt tensioner sticks out just enough to clip the side of the stop switch at the front. Again I'll try trimming this piece as well.
Going in the more common direction ( left on x and front on y) there are no i
I really like the concept. If there were no hitting issues I would recommend that these be included with every Ultimaker as a stock part!
