Re: Omni 1530 ordered and ongoing log of the process
Ugg - Ok so its cutting fine but I still have an issue with the auto tool height. Well I think its more a combination of things. 1) is the sensor and its mounting bracket are a little off level and a little flexible. Not a lot but a little. There is because of this or due to the sensor itself a bit of variation on the measurement. Mostly in the .05-7mm +/- range over 3 tests I did (so up to .14mm between 1st and 3rd) - not horrid but not great. However my largest router bit (for surfacing the table) seems to have the most variation. Its up to .55mm - which is on the horrible side. The probe is supposed to be in the .01mm accuracy (per ebay).
I suspect this might have to do with slight rotation of the cutters combined with the slightly off plane sensor. The practical result is that my table should be '0' for all cutters and as it was cut with the large bit at its '0' then all the other should be skimming the surface. But right now in testing the next bit comes in to its height offset '0' and its cutting into the table slightly (spoilboard so not a big deal overall). But if I move or alter the sensor arrangement then I need to redo parameter 3411 which need access to the vacuum grid (now underneath the spoilboard).
ok - I just checked - yeah its out of plane more than I thought (also note that it won't work well for large bits as the bit really needs to be under the diameter of the pad (which this bit is not). The steel angle that the probe sits on really should be a tube for rigidity.
Anyhow on the great news side of things (and more relevent for anyone considering buying a machine), Jack was great tonight with Albert in Tech support in getting m-codes set up for my vacuum blower and dust collector. Still trying to get a few more things assigned m-codes but they were great and fast (once I convinced them it was possible and shouldn't be very hard). So on a practical level, this means I can set up a large time consuming job and leave it unattended if needed and the vacuum will turn itself off. Also really helps you know when the job is done as the spindle noise can get lost under the vacuum.
In case anyone is wondering, I'm the twin of the other gfacer on cnczone...
