Parameters can be accessed by pressing MOD repeatedly until you are prompted to enter a Code, which is 95148. Care should be exercised with machine parameters. In this screen, pressing EXT then NO ENT causes a full dump to serial. Pressing EXT and ENT makes the machine look to read them, but sending them as an ASCII file via a terminal program doesn't seem to work. | Parameters can be accessed by pressing MOD repeatedly until you are prompted to enter a Code, which is 95148.

Set up the tool chain. Ryan has succeeded in hacking a custom post-processor for Aspire. He fixed the previous problem with arcs. However, it seems the machine slows down at the end of each G-code line, so designs consisting of lots of short line segments have a very low effective feed rate. | Set up the tool chain.

Ryan also succeeded in hacking an Autodesk Fusion 360 / HSMWorks post-processor. This makes far more sense for this machine. Multi-tool jobs are supported, including milling operations and peck drilling canned cycles. | |||

Software limits for X, Y, and Z travel needed to be reset. Current values are determined by running the machine to the e-stop hard limit, recording the position, and subtracting 0.4 mm, except that the X hard limit seems like it isn't positioned properly and may be crushing part of the cover so it was set arbitrarily. Current values are: X: +12 -442.58 Y: +7.29 -300.18 Z: 8.13 -116.55 Note that these must be set both in the machine parameters (#44 - #49) as well as in the user soft limits. | |||
Spindle brake does not appear to be connected. No, it does appear to work. There is a switch to enable or disable it. | |||
