I am using carveco/artcam for toolpath generation and linuxcnc for control. Blender and fusion360 for 3d.
I thought the same as you mentioned, and I am trying to experement with artcam settings....
I will give it a try
Thanks for taking the time to help

Good day
Please see photo
I used end mill 3mm for finishing
feed rate 25mm/sec
step over is 30%
spindle speed 8000 rpm
depth of the cut 8mm
I could not edit my last post
I found the limits
I do not see the depth of cut per pass (stepdown) figure used in the chip load calculation
Very helpfull
I will use this method for calculation.
Good since you are using metric units
what is the limit surface speed for steel and carbide tool in metric?
And the chipload per tooth...
I am trying to understand the basics of milling while trying to put my DIY milling machine into use.
trying to mill 20 mm circle cut (2d tool path) in 8 mm steel plate
I used the following...
glx does not seem to make differance.
but youtube does
just open 6 you tube videos and wait awhile
I decided to have bt-30 spindle but not clear on the motor
AC- servo or induction motor. The induction motor seem heavy and I have 16 mm ball screw on the Z-axis
The other thing do I need to...
I am little behind.
I could not take the video.
The 3d printer takes long time to print the parts. I am using 100 % infill. I saved about half the time after using. 6 mm nozle.
The...
I ordered from Aliexpress only one time before. It took over 90 days to recive the package. That was a while back during the begining of the COVID19. I was hoping they improved.
All my orders from...
I can not value enough all the posting here which helped me understand.
I feel more confident now than a couple of days ago.
Thanks all
many thank
I saw this video.
He bought a bt-30 ATC one year later.
Yes I was reluctant between AliExpress and ebay.
What I observed with ebay that while they have large selection, they...
Great
Almost there
I have the spindle you linked as item in Aliexpress basket.
Now the last question (haha)
I have seen some milling heads spindles specifying a pull-stud M12x45 degree.
very good
So I will read the specs about the type of bearings they have and I will check with the vendor.
I already sent the vendor a question about the draw bar, they said the draw bar not...
I want to buy BT-30 power head from this link
https://www.aliexpress.com/item/32819388833.html?spm=a2g0o.cart.0.0.44f03c00OezPmD&mp=1
I want to make sure that I buy the matching tool holder...
very good
I will test my nema-34 Z axis stepper motor to see if it can lift 35kg (The weight of bt-30 + )
if it can, I will place the order
many thanks
many thanks mactec for very direct replies
OK
Now I understand that I have to use something like bt-30 power head belt driven. I am only worried about the load on the Z-stepper motor.
I am...
hello
I am 90% done with my milling machine. I made it rigid enough for 8 mm tool milling steel
My question
I found a motor that weigh around 15 kg and I want to attach ER20 to the end of the...
I will give it a try tonight before tossing that board.
I do nothing now without crimping and proper solid connections. I learned the hard way.
Thanks
Lose/improper connections in my case has caused the weirdest results including drivers and motors failing.
In one case I found that I had partialy fucnctioning break-out board because of a lose...
Did you try to swap wirings/drivers/motors?
Very good
Thanks
I have a break-out board that came with the equipment.It failed and I replaced it with Arduino Uno/v3 sheild. But I control the spindle motor outside the board and just...
Thanks peteeng
Yes
I will start with a safe current settings and when I build the x/z carrage, I will test it on temporary runway using 20 mm ball screw with 2 ball nuts (not back to back but...
my stepper datasheet says 5.5 Amps per phase. driver max 6 Amps
trying to figure what current limit (Amps) settings I should set the driver at.
The stepper motor data sheet (attached) says 5.5...
Yes
Those are the ones
After seeing your post I grabed my only lipo connector and it fits. I will need 9 of those, three per motor.
I know where they sell those localy. I have to drive 300...
I have 3018 router (toy). last time before the issue I am going to describe, I pluged in the power cable to the driver board
and observed some sparks coming out. Then I corrected the power supply...
I can not thank you both enough
So the response time of the system improves with a high rated driver.
Thank you all
I have a stepper motor with name tag of 1.2 Amps
not sure if this is per phase or for both phases.
Any way I set the tb6600 at 2Amps in order to get it to a reasonable warm-hot (I still can...
I could have stopped the reporting here, but I did not feel comfortable in case someone reading I might confuse him.
I find several issues
while it is true that pumping the acceleration up has...
