Hi all, I have a couple more issues with Hm2 The PID parameters are very different than Hm4
Heres what worked on 4: P = 110 I = 2 D = 0.5 FF0 = 0 FF1 = 1.05 FF2 = 0.008 BIAS = 0 these gave me a following error of .003 at 350 ipm and less than .0002 at 30 ipm the same numbers on 2 created severe oscilation this is not such a big deal as I can retune but it would have been nice not to. I tried these numbers on 2 and could move the machine slowly P = .4 I = .6 D = .15 FF0 = 0 FF1 = .0 FF2 = .000 BIAS = 0 That is a big difference and I know Im not done tuning but I dont think that I will be going from a P of .4 to a P of 110 I dont mind retuning but before I do I want to know if there is something I missed Here is the other thing,I tried to home the machine and it searched for the limit switches and hit them and started backing away and just kept going I let them each move an inch and stopped them.I know that I passed the index at least 3 or 4 times so where do I find that setting? When it hit the limit I did not get the little arrow beside the read out to note that I was on the switch This is in the .ini file of each axis HOME_OFFSET = 0.02 HOME_SEARCH_VEL = 0.30 HOME_LATCH_VEL = -0.01 HOME_USE_INDEX = YES HOME_IGNORE_LIMITS = YES Thanks in advance Terry ---- Msg sent via CableONE.net MyMail - http://www.cableone.net ------------------------------------------------------------------------------ Register Now for Creativity and Technology (CaT), June 3rd, NYC.
