Re: double check my numbers and follow error

i meant i put in the new numbers for counts per rpm and counts per degree i also punched in the new number to the factor and all seems to be working now just fine i hate my 75$ construction calculator just rounds things real easy and online calcs are kinda silly to use. that and a crazy long number....

thanks

i put that in and S1000 (MDI) but get 798 actual rpm?

double check my numbers and follow error

ok so now i have a real nice 2000P/R encoder on the spindle servo the servo is now 14 tooth and the spindle 26 tooth. 0.53846153846 ratio so invDistPerCycle is 0.000375 count/rev in kmotioncnc 14814.8148148 and A axis count/deg 41.1522633722 my god my brain is exploding might get a dam 28 tooth for ...

Re: weak servo / maybe commutations off?

i did play with different amplitude a bunch and it would vary the results quite a bit. i tried from 200 up to 1500

great on the 5V

Re: weak servo / maybe commutations off?

300 loops. what does this mean though? the servo only turns a couple revolutions and then is enable i am waiting to change a setting like like and make some fire off the board! lol :lol: i read the 5V only has 100Ma each? "(4) +5V outputs are available to power low current (<100ma) external circuitr...

Re: weak servo / maybe commutations off?

quite the opposite, i see lots of it! the omron encoder is saying 160 mA max consumption. can i run this off the 5V on the Kanalog board? or grab 2 of the 5V pins? { WaitNextTimeSlice(); k+= dk; Write3PH_DACs(ch,A, k/1000.0); // move the pole zmark = ReadBit(Z_BIT_NUMBER); if (!zmark && ignore>0) ig...

Re: weak servo / maybe commutations off?

i looked over the phase find program and cant see where i can adjust for the ignore :( i ordered a new omron 5V incremental encoder for with 2000 counts so it will make some numbers easier and also i have another servo pulley showing up to make the servo/spindle ratio a smooth 50% under drive :D htt...

weak servo / maybe commutations off?

i notice my spindle servo does not have the low rpm grunt it did when i first got it working runs fine at higher speeds at first i could go 20 RPM and not be able to stop the 6" chuck with my hand now i can easily stop it. would CommutationOffset have some control in this? using 2 DAC channels to dr...

Re: user button to send X and Y axis to position 0.000

ok i saved the KflopToKMotionCNCFunctions.c on the desktop with my other C programs and all is working great
there might be some other stuff i want to have run in the MDI like this later
thanks! ;)
