Few more tests today
Pushed the feed up to 800mm/min with the 4mm and seemed to go better I think
Tried 6mm for the first time 700mm/min @ 24k rpm .4 DOC and seemed pretty good as well.

Could I...

Cutter is an upcut if that's what your asking.
2mm cutter at 13k rpm at 1000mm/min .2 doc. Works good
4mm cutter at 24k seemed to work at 400mm/min .4 doc certainly would not work at 1000mm/min....

Thanks for the reply peteeng, I have been cutting fine with a 2 and 3mm cutter at 13k rpm and .02/.03 DOC. My problem was with G wizard and the results I got. It doesn't seem right and certainly...

No one can offer any assistance?

Does anyone know if the g wizard results above are correct or have I not inputted something correctly and do the numbers I ended up cutting with seem ok, I know it seems to be cutting ok but just...

Anybody?

Hi guys back with another alloy cutting question, I have had success cutting with 2 and 3mm 1 and 2 flute cutters. Recently I got a new spindle with an er11 collet and have got a 4mm and 6mm cutter....

Thanks mactec, I already have g wizard but it's expired so was hoping for ball park figures but not to worry I will figure something out. I went through a bit of trial and error with 2 and 3 mm...

What sort of feed rate, spindle speed and depth of cut would you recommend with those cutters mactec?

I'm looking at some 4mm and 6mm cutters, reason I haven't got any bigger as I wasn't making anything that required bigger, but there has been times where I wish I did for certain situations such as...

It was not even hitting 1 amp with those cuts. I don't have any cutters bigger than 3mm as I've never needed them, now that I have an er11 collet set I will think about bigger cutters. I am happy...

Ok so was able to cut some test pockets today in both aluminium and wood, spindle performed great. The main thing was I wanted it to perform well in the alloy test and it did. Only doing small cuts...

For sure, I am not even sure I will really need it. But will see. Thanks mactec and ericks for helping out.:banana:

The tacho seems to be about 50 to a max of 100 rpm out compared to the vfd, but to be honest its an $30aud ebay tacho so I don't know how accurate it is, the vfd may be right or the tacho may be...

Thanks mactec, yep I had thought maybe I had done something wrong before but yes now 114 was able to be changed. The vfd readout for rpm seems to match the tacho so do you think I still need to alter...

Ok settings changed. My ebay tacho has arrived and to my surprise it seems to be fairly accurate, give or take a few rpm, within 50 to 100 rpm i would say. I had tested it before I changed to the...

No definitely helping me understand more about this drive although I'm still a little unsure exactly what some of them are doing, but really haven't had much time to sit down and review everything,...

Yep I think that is the best but nothing wrong with getting everything else right and as I'm new to the whole thing, any help from you guys is much appreciated and hopefully next time I will have...

I am not sure at the moment as I have been following mactec's setup parameters and some of the settings are not working as he expected so waiting his reply to my post above. still waiting on tacho so...

P102=0
P801=0
P111=15
P112=2.5
P113=8
P114=1.2 this cannot be set to 120 max is 2.5
With the above settings, j2 set to I and
P101=0 and P101=1 no pot control and full speed on initial power...

Thanks mactec for the help, Ok tried again and yes it goes straight to full speed, BUT, if I hold the down for a couple of seconds the speed goes down and once at min rpm it will remain at min while...

Ok this is done but p101=0 made it go straight to 400hz full speed and no control from the pot. So I changed it back.to default - 3
I already had p100=400
changed p801 to 0
Changing p212=24000...

Yep I did p100 but not yet p101, at work at the moment

Will change p101 and p801 tomorrow.
No I get that the rpm readout may not be what the motor is doing, p212 was confusing me as i was not...

Ok I think my dunce cap is slowly coming off and I'm getting what your saying, forgive my stupidity, but it never occurred to me that the motor is doing what it should but the vfd may not be telling...

Ok so are saying that the motor is spinning at it's maximum rpm regardless of what the vfd says?

Second - if first is yes then all I'm doing with the settings in the vfd is getting it to read the...

Yes mactec, changed p100, but didn't seem to make a difference.
ericks
I am hearing the correct difference in sound when I turn the pot to change speed, motor sounds slow, turn the pot to max...

Again and I'm not sure how else I can explain it, I am hearing the difference and seeing speed difference. But please read what I am saying

There is no difference in sound if I have everything set...

Thanks mactec, yes I followed your settings from another post to start off with and have now amended the ones you posted here, but I seem to have no difference in what I hearing.

Yes I hear this. Maybe Im not explaining myself well enough. Lets focus on one thing, max rpm and sound of motor at max rpm.
Ok vfd reads 24000rpm, motor makes a certain sound.
Change settings - ...

I realise this but I am saying when I change the settings I am getting no audible difference between said rpm's my problem is that I believe I should be hearing a difference in sound of the motor at...
