So I’ve been trying to dial the Maslow in (I have a metal maslow) and when investigating the slop in the Z-axis i noticed that my two rollers closest to the sled are different than the other 4 rollers. On top of that, one of them is completely cracked off. Anyone ever source these rollers or have a good idea where to get them?
Also the cable connector that attaches to the Z-axis motor has cracked and the white wire comes out. I’d like to find a replacement for that as well.
The wheels closest to the sled are mini v wheels, so that they clear the chain mounting brackets.
The extreme version is less likely to break than the delrin version.
Not sure about the cable connector.
not sure why you raised the linkage arms up so high? Better to move back the top motor bracket.
we sell replacement z axis motors, but it looks like the main issue is there is nothing supporting that cable. best to zip tie it to the structure to prevent it from being torn out.
From what i read on the forums people were raising the chain 3 - 3.5" off the workpiece. I think that is about 3". I was getting significant sled tilt when operating so i pushed it higher and it seemed to help. How far off the workpiece would you predict it to be?
The motor seems fine, its just the cable. Do you sell replacement cables?
well a common mistake is to build the default frame with the top bar out too far and then compensate for this too far out bar by moving the linkages out too far as well. that is most likely your issue.
many posts on this forum are using a light 2 lbs wooden base. the metal base we supply is 6x heavier and thus the center of gravity is lower. rasing the linakges too high might introduce more slop it’s not recommended.
I’m not sure if these photos convey it well, but the back of my motors are only out from the frame the width of a 2"x6" and a 1". So 2.25" plus the distance from the sprocket to the back of the motor. That doesn’t seem too excessive?
it might work perfectly fine, but the whole reason for the metal sled is to lower the center of gravity, adding spacers defeats that a little. I’d get rid of the 1by 3 wood block and get it as low as possible, but if working fine then that is great.
if your sled tips back when you run off the bottom of the workpiece, then the chain is too low. If the bottom of the sled lifts when the sled is moving up, then the chain is too high. When the sled is balanced and the chain is at the proper height, you can cut pretty close to the edges and the sled won’t tip.
