This afternoon I finally got a chance to start dialing in the CNC table. I wrote up a simple Gcode file to do a few major traverse of each axis and then a couple of cut moves, one straight one radius. Turns out that 300ips == badness.. lost steps and just sort of jammed up the steppers. This was the default set into the machine. Got to learn quite a bit about resetting the and re-zeroing the machine. Turns out 200ips is a fine traverse speed. I’m not worried about minimizing the program time and can live with a slower traverse speed. I think the next thing I’ll do with it is to make a holder for a pen and determine if it is calibrated accurately for axis travel.. In other words if I tell it to move 10 inches how much does it actually move.
Instagram Feed:Swapped the leather belts for 3/8inch round polyurethane belting (85 Shore A durometer). Result: cleaner smoother cuts with better feedback to the drive handle. In other words less slipping in the drive system. Some of you might notice that the leather belts were twisted and these are not. The reason for putting a twist in the leather belts is to increase angular contact with the pulley and thus friction and the poly belts don't need that. Alos in this system 2 twisted belts has the same directional result as 2 non twisted belts. #podforge #wip #watchmaking #engraving #guilloche #shoplife #oldtools #horology #jewelryPlaying around with the new machine. Seeing what still needs adjustment and getting used to it. #podforge #wip #watchmaking #engraving #guillocheFinally today....assembly!!!! For all those wondering, it is a straight line ornamental engine by Hall. Most likely made prior to 1920. The leather belts will get replaced with less temperamental polyurethane round belts. #podforge #wip #watchmaking #engraving #guilloche #shoplife #oldtools #horology #horologylife #vitreousenamel
