Phase 2 Rebuild
The “moose in heat” sounds my printer makes prompts me to whatever I can to restore the peace.Above: First mark the location of the stepper on the inside of the rail Right: loosen, but do not remove, the deck screws that hold the rail in place as well as the two screws on the right angle brackets. The rail slides out. |
|
The marks were scribed into the magic marker at equal distances from the ends of the rail |
I used a table saw with a carbide blade set to 1/16 inch depth to make multiple passes over the area. Then filed off any rough edges. |
Left: I removed a cork strip that was on the back end of the Y
stepper motor and then re-installed the rail. With everything lined
back up and tight a piece of paper easily slips between the Motor and
the Rail. |
You will need a TORX driver to remove the screws at the end of the rail. |
Expect them to be a little tight, there are traces of thread -locker on the screws. |
Above: The end block is tight on the rail. I used a very large screwdriver and the SIMO carriage to remove the end block. Right: once the end block is free it will rotate. |
|
Above: Pull the end block free from the feed screw. Right: continue, with a smaller screwdriver this time, to remove the SIMO carriage from the rail. |
|
Left: while there is a "shiny" line down the middle of the SIMO carriage, there are no signs of rubbing on the coating on the feed screw (above). I don't know if the shine is from very very light contact (enough to make noise, but not show wear) or is from the manufacturing process? |
|
Left: Carriage mounted on my Sherline Mill bed. Above: Finished milling shallow slot |
Left: Re-attached the AB Nut, but left the screws loose Above. Carriage re-mounted on rail. Tighten the AB nuts now. |
|
Above: Replace the end block. Alternate tightening the screws so that it sits squarely. Right: Front rail of the base has been removed. I've already removed the screws from the Y-rail end block. Process is the same as for the X-rail. |
|
With the end block removed the Y-carriage slides off the same way the X-Carriage did. When re-installing the carriage I left the screws holding the AB nut loose until I had the carriage seated on the rail. Then I reached in thru the slots in the top deck to tighten them. Re-attach the end block and replace the front base rail and you are done. |
