Hi Tom

Thank you so much for your help and patience , with me on this project .

I was starting to doubt whether using a Kflop/Kstep/kanalog set up to retrofit a CNC mill would be possible...

Tom

Works almost perfectly :-) , thank you

S =1000

in CCW ramps up nicely to roughly 1200 then down to 900 and then stabilizes at 1000 +/- 20 rpm and ramps down to Zero when the off...

i cant seem to find where the FACTOR value is is the 200 that needs changing V =200 in the step/response screen ?



This works perfectly




i will check into this , also on the last check...

Don't think its just picking up one hole , if we take measurement below 1680rpm @ jog3=100, 50 holes in disk

(1680 x 50) / 60 = 1400 . scope measured 1.34 - 1.42 KHz


Done


I Don't...

Tom

Yes Scaling is still -0.02 as in the step/response screen that gives the encoder the correct reading on the axis screen

Spindle max 3750rpm with motor @ 7150 rpm

Good Morning Tom


Found it thank you

Hi

Thank you

that is how i did it, i managed to do it in 2 cuts top part first , down the taper 35mm depth and then the bottom half all the way down to the model bottom , leaving the tapered...

Thank you for the video , didn't really help much I'm afraid .

i am trying to machine the outside not the top face

This is the article that i have been following since last Friday , have tried all methods suggested and cannot get S to change it is always full speed in kmotion.exe ,. jog3=?? and DAX0=?? works...

Hello

I am just starting out using HSMworks within Solidworks and have a machining problem as per the attached screen shot , the part has an angled bottom and i only want to machine the outside...

#define PC_COMM_CSS_S 113 // S speed setting in inches/sec

Wasn't in the PC-DSP.h that i could find . i have added it and the change from CW to CCW is slower now like it is ramping down...

Hi Tom

Same result as my previous try's , will turn on ok, but not stop ,
with trajectory screen @ 200 cnts/rev ,kmotion screen reads 70 rpm when S is set to 100rpm actual spindle speed 3750rpm...

Thank you so much for the help , i think i have it where it is workable , now to set it up in Kmotion.exe

i have set up M3,M4,M5 and S in the tool setup , using your example in the CSS...

JOG3=66.66 click Send seems like a delay of a second then ramps up to approx. 1500 rpm then down to 800 rpm over another second then stabilizes at 1000rpm

VFD is a Lenze 534 speed...

Tom

you were correct i was using to small a P gain

new plot attached


Sean

Hi Tom


The plate has 50 holes in so i set input gain at 1/50



Max Spindle speed is 3750 , so that would be a max V =250 , so i should use something smaller than this ie 200

yes the position is moving looked like missed counts or something weird , checked factory installed holed disk and was seeing +/- 0.25mm runnout have remounted it today and not missing hole edges ....

Hi Tom

1 thing i have noticed when doing the step/response is the DAC voltage goes +10v then goes - 10v and stays there until i disable the axis ??

Cannot see any axis move should it be in the lower the S box ? . i can see the encoder pulses working in encoder 3 A/B in the digital I/O screen



changed the input gain to -1 trace attached

encoder input set to 1 ( where would i see position change ?)



i have set the config screen to encoder input and FF =0



see plots , no movement

Tom

if i put FF = 0 nothing moves , at 2047 it gives me full speed

ground seems to be floating at 1.2v between the Kanalog and VFD ?


Sean

Tom

Managed to find two opto sensors in a draw with built in triggers and 10K resistors

i have added the encoder trace before connecting , not sure 4.8v is ok into the kanalog encoder...

Tom

Thank you for your reply , after a few hours searching i found a thread that mentioned using an RC delay to the signal. it kind of worked but the delayed signal was more rounded that the...

Hi Tom

Hopefully the last Question regarding this build as almost everything is functioning perfectly

i have configured my VFD servo Drive as an axis with DAC 0-10v control and is all working...

Thanks Tom

Have assembled the Y axis and have what i think are good settings . the Y axis is identical to the X-Axis , so i am thinking the higher start stop error maybe something mechanical on...

Tom

attached image seems to be about as good as i can get it.

Vary much from the settings and the start/stop error goes up or the motor stalls

Thank you so much for todays help
