Thanks EddyCurrent
I think that's the top speed off this spindle or maybe it's 11000 I will have to check

JAZZCNC here are the settings that cam with the machine
x and y axis steps per 400... velocity 2000...acceleration 200
z axis steps per 400....velocity 800.....acceleration 100
step pulse 10 for all 3 axis
dir pulse 3 for all three axis
what do you think?
Every machine is different and motor tuning is dictated by the machine so I can't be specific with motor tuning and you'll just have to play with it.Quote:

To do this just Copy your existing Profile in Mach Loader. This will give you an exact copy of the current Profile with all the same settings but under a new name which you can then tune to suit the type of work your doing or just for playing around with.
I have several Profiles tuned in differant ways.? So when doing mainly 3D type work I load the profile which has motor tuning biased towards acceleration rather than velocity.
Just remember when tuning motors you can't have high velocity and high acceleration, often you'll have to lower one to raise the other.
I also duplicate these Profiles and setup for Imperial units for when cutting G-code set for Imperial units.
The Code I gave you has a Max cutting feedate of about 800mm/min and the moves are very close together so high rapid speed between moves doesn't help has you never reach it. Basicly the machine has to accellerate to full speed then slow down again for next move and with such short moves no way can it get to full speed. The speed it reachs will depend on the accelleration so for jobs like this with such short moves then dropping the Velocity and raising the Accelleration will make a big differance to overall cycle times.
Setup a profile called 3D and try it. Drop Velocity to say 1500 and Accel to 500-600 and see the differance, Don't go quite so high on the Z axis and play about with them. If you start getting lost position or stalling motors then you will have gone to high on the Accleration.
Ok I will have play with it thanks
Hi
I had a play today and Drop Velocity to 1500 and Accel up to 600 and it cut the time from 1h 30m to 1h 15m and the motors seem to be ok. The cutting tools you get with this machine are useless is there anywhere that sells good quality end mills and engraving tools? Thanks for the advice guys.
I have the same machine... but I can not find tools.!!
Second Cut On My CNC 3040, Using A 60deg V Bit.Drop Velocity to 1500 and Accel up to 600 and it cut the time from 1h 30m to 1h 15m and the motors seem to be ok.In the first cut video I used a 30deg v toolhttp://youtu.be/NpzHUm8Y4Is
Here's toolpaths suited to your cutters 30deg and 60deg but be aware they will cut much deeper has I limited the cut depth in the one you already cut.Quote:

Hi
Thanks JAZZCNC I will give it a try
how to reverse the rotation of the spindle?
My is 3040T and the spindle is a ER-11
Why would you want that ?, the collet nut is designed to rotate forwards, i.e. it is trying to tighten all the time.Quote:

I've not seen those, all I've seen are 'up spiral' and 'down spiral' cutters but they all rotate in the forward direction.

my turn in the clockwise direction.... it is right that there has to turn in that direction??
thanks for the reply me man...
Looking down on the machine all cutters should turn in the clockwise direction, same direction as a drill would. The up and down spirals are in opposite direction but they both cut in the clockwise direction.
Did you look at the link above to trend-uk.com ?
then I bay something wrong... :(
Ok so lets first determine which way your spindle is actualy spinning.? It should be spinning in the clockwise direction does it.?Quote:

instead the cutting tools have in counterclockwise
on that site you sent me .. What can I take to have a complete kit?Quote:

I'm not exactly sure what you mean but this site might explain it in your own language;
Mandrini per Pantografo, Utensili Diamante, Frese per Pantografo - CMT Utensili
Sì quel sito io ho visto ma non sono sicuro quale utensili andrebbero bene per il mio mandrino ER-11
watch this video if you understand what I'm asking.... if you see tool runs contrary!!
The biggest you can use is a 1/4" shank with the right colletQuote:

Yes I can see the tool runs contrary (anticlockwise) but you don't want that. If you want to use Italian to explain it better I can translate it to English with Google or Babylon.Quote:

Non riesco a capire.. qual è la colpa è la mia oppure della macchina?
Tutte le frese hanno bisogno del motore a ruotare in senso orario. Stai dicendo che c'è un problema con il vostro motore e non è possibile farlo anche in senso orario?
Sì... come posso farlo girare in senso orario??
E poi a te come ti sembra e giusto che il mandrino gira in quella direzione??
Si tratta di una nuova macchina ? È la prima volta che si utilizza? Come il motore è controllato da un INVERTER ?
Forse è questo provo a invertire i figli

Hanno lasciato i fili invertiti .. Man ho risolto il problema :)
Eccellente, buon divertimento
Grazie di tutto .... :)
For everyone,
Just for reference, this must have been a new machine and the problem was the spindle turned in the anticlockwise direction. It was a 2 wire DC spindle motor so the solution was to reverse the motor leads as described here, http://mambohead.com/wp-content/uplo...ion-Manual.pdf pages 20 and 26
Yes I do not I changed because I was afraid of burning the spindle.... but now it seems that it's all right I changed the 2 wire DC spindle motor + and -with and working properly .... thank you very much EddyCurrent
