Robland X310 Axe commutateur d'allumage

Here is the spun text: I am providing you with the design for the transmission axis between a Salzer T225 rotary switch and its button. This is intended for a Robland X310 wooden combination (or any other device using this switch).\r\n\r\nThe first version made of ABS without metal reinforcement held up well but broke like the original axis due to a transverse impact on the button. However, the problem with ABS is shrinkage. You then need to make an expansion under CURA. Two or three attempts before finding the right ratio.\r\n\r\nDue to lack of time and not having noted this ratio, I redid the axis in PLA (infill 100%). It broke (see photo) after a few rotations under rotation constraint.\r\n\r\nI therefore modified the design to incorporate a small flat metal rod with a drop of cyano UV glue in its housing before inserting it (is this useful ?).\r\n\r\nThe rod, made of stainless steel, comes from an old car windshield wiper (not flat-blade). You must always recover these rods which can serve for many things ;-)\r\n\r\nThis reinforcement seems to do the trick after several dozen tests.\r\n\r\nIt may be necessary to reduce the rotation force of the switch by removing two of the four recall springs. To do this, you need to remove the locking ring that is clipped onto the body, then remove the plate held in place by two screws. You will see four springs mounted diagonally around a recall star. Remove one pair of springs.\r\n\r\nThe transmission axis design between a Salzer T225 rotary switch and its button is intended for use with a Robland X310 wooden combination or any other device using this switch.\r\n\r\nThe first version made of ABS without metal reinforcement held up well, but it broke like the original axis due to a transverse impact on the button.

The rod is inserted into the housing with a drop of cyano UV glue, which provides additional reinforcement.\r\n\r\nThis design modification seems to have solved the problem, and I was able to test it several dozen times without any issues.\r\n\r\nHowever, if you experience problems with the switch's rotation force, you may need to remove two of the four recall springs. To do this, you'll need to remove the locking ring that is clipped onto the body and then remove the plate held in place by two screws.\r\n\r\nOnce you've removed the springs, you should see four springs mounted diagonally around a recall star. Remove one pair of springs to reduce the rotation force of the switch.\r\n\r\nThe new design with the metal rod seems to be working well, and I'm confident that it will provide reliable service for your Robland X310 wooden combination or any other device using this switch.
