General Mach Discussion / Re: Milling letters/design on arched face surface

« on: December 22, 2011, 04:23:01 PM »

I need to do a similar task so will be interesting to see what folks post.
I was going to place the text on the 3D surface and restrict the cut depth so it only cut the letters ....I think that will work
but have yet to try it. That eliminates the need for say using an A axis and wrapping it like with Wrapper.
Know nothing about Master cam though.

Your xml hangs up my computer every time I tried it. Can you repost it again?

If you don't re-zero you are starting out with some error around .020", so that error is going to accumulate by that error for each run.
If five runs it would be out by say .1". The question is how do you reduce that intial error. I have found the lead of the screws on the Sherline to be quite linear.
So some of that error can be due to the backlash created in the thrust bearing / washer and the nut ( i'll assume that the coupling is tight and not slipping any ).  
 I  think it is more than .001" , Sherline says .003 to .005",  but that's just my nickle, ( you would need a very tight Sherline to achive that ...gib, preload on bearings, and nut adjustment) and when that is done your using a lot of available motor torque. I think the stock ones are around 135in oz. You can be loosing steps and not hear it.

The thing you do have going for you is that it's repeatable. So cut the accel to 2 and velocity to 10IPM for a test and see what happens on a test run.

tipit,
Not here to spar with you and understand your frustration. We can't assist you with the license problem.  
Let us know how it turns out in the near future by simply saying that the problem was or was not resolved.

[Thanks Gerry, My Bad.....

tipit,

if anyone of you is using this software with a legal serial and can send it to me

You need to get in touch with the guy that sold you the software to resolve the license issue.
Getting a license not assigned to you is not the way right thing to do.

Wish you well for the holidays,
RICH

I have sent a few Emails to Rich and I didn't get any replies.

What Rich did you send email to? It was  not me and I have never sold any wizards.
That said...... What kind of scam are you trying to pull by asking for someone elses serial number to software.

What say you?

Is the Sherline stepper or servo driven?
What contoller are you using?
Are there homing switches and what kind / from who?
Post your xml file.

I would imagine that if you started at the same point, positioned the machine properly / the same way, and re-ran the program the second time, you should end up repeating rather closely
to what you did on the first run. Not progressively get worse. It should be within some tolerance of your milling machine.

I installed a brand new  Sherline Lead screws / nut along with their backlash lock and preload system on a Sherline lathe.
There was nothing wrong with the lead of the screw but trying to maintain backlash at ( .001" no way....maybe .003") was almost impossible over a short period of running time.
Same goes for my Sherline Mill. Nice to play with ...so i hope folks don't think I am bashing Sherline.

I know nothing about EdgeCam, but, the machine will do what the code says.

Click the "GCODE" button near the reset button on the screen for a list of gcodes. Also may want to have a look in the manual.

Your driving 2 motors at 3 amps each using a  power supply which is 24V @4.5a. I would recommend that the power supply have the current capability for  both motors which would be 6 + and an increase in voltage also. That will increase the motors preformance. Without a motor
curve  it is only a guess on available torque and rpm unless someone has experience with that particular motor. You have not noted how the motors are wired and that can also make a difference.
