Start by taking the aluminium cover plate off the front of the turret (M6 cap screws - 3 off) There is a large O-ring that may fall out from behind it. Lets start with aligning the spindle axis. You need to manually align the spindle axis and then reset the spindle resolver. If we're still on the right track, then this is what you need to do.

If you've checked this and you're sure that resetting the resolver isn't going to solve it, then feel free to tell me that I'm barking up the wrong tree :-) I just remember that the spelling was all wrong. But because of the missalignment of the tongue and groove driving dogs, the tool changer gets jammed and gives some sort of message "? TOOL CHANGE EXCEEGN!!?" or something like that. Then it gives the signal that it is in the correct position for a tool change and the turret starts to turn. It still returns to the offset in it's memory and since it doesn't know that the belt jumped, it thinks it's right. Resolvers map their position using windings in an electromagnetic field and encoders map their position using a glass disk with etchings in it.Īnyway, so now the belt is a couple of teeth out and instead of the motor lining up the spindle, it lands up getting it wrong. The machine "knows" this position only by remembering the offset on the spindle resolver, relative to the motor's home position.

This will allow the tongue of the drive to slide out of the groove of one station's spindle and into the next. The machine is supposed to orientate the spindle, so that the flat driving dogs in the hub of the turret line up parallel to the X-axis. Or if the belt has recently been change and is still a bit too slack.

It normally occurs when the drive belt has skipped a tooth or two - maybe on a large diameter tool or if a tool gets stuck when drilling solid material. Our machines have had this problem a number of times. If i am not making much sense, sorry, i did not sleep from yesterday 11AM, so running on fumes now.Īt some angle the dro starts to go up slowly to a certain point then just shoots up to sky high values, and sometimes only sometimes could go back before reaching the shooting point.If I understand your machine's problem correctly, when you choose to change a tool, the turret is jamming before it can reach the next tool. Under some combination of the above, got the dro to count UP regardless of the direction of the spindle. Tested with added "s, l, f, u" etc as per hostmot2 manual, some noticable change in halscope, not usable I did all testing on the spindle encoder, i testet changing rawcounts to count> no noticable difference, changed clock frequency>100 kHz not good, 200 up to 800kHz works as noted above.Īdded ssi.countsperrevolution no noticable change, i did connect them today to the configured port but i got no response from any of them, more investigation is in order. I did not test the axis encoders, i have to do that tomorrow. PCW, i did try 12ge with the spindle encoder, got nothing back, with 24ge i get random readings, with 32ge still random but less jumping on the dro. Please Log in or Create an account to join the conversation. At first glance it looked way more complicated than the hal settings i am using, so i might give that a try in a day or two. I did find another thread on this forum today explaining some other SSI encoders that had a different way of functioning in hal, active users were PCW, you, and another member. Tested all i could think off but no matter what, it gives fuzzy readings, and at a certain point in rotation, it just stops sending pulses, so i gues it must be lower/upper type. Long X axis is 4096x4096 but has another wire fro direction.įound the above attached pdf, so they are SSI and grey code, also the frequency is recomended to be at 200kHz. Spindle encoder is 4096 counts per revolution but can count only one rotation. Not to be mistaken for counts per revolution.Īxis encoders are 4096 counts per revolution and can count up to 4096 rotations. This is with the spimdle encoder, same typea are on all axis except the long X, but different revolution counts.

Yes that is what i get, and i can see the pulses with halscope, tested for 3 hours today to get something useful out of it but no luck.
