Hi Shorty I am completely new to the world of CNC so I can't make any comparisons yet. Eventually I will try out TurboCNC and DeskCNC but for the moment I am...
Hi, and a happy new year to ya all. Would like to send out an warning to everyone the has recently ordered steppers from Sherline. I ordered 3 steppers type...
Jerry, Actually I am still using Turbocnc on the lathe, I have never had a problem with it on that machine, I have used the computer from the lathe on the mill...
Vector lathe roughing and finishing does heel avoidance automatically when cutting "behind" a larger diameter detail. You Know fred I am getting a little...
... part of my problem, I was not setting up the tool angle parameters correctly. Once I done this I no longer had the problem with the heel gouging. Thanks....
Fred, That is neat and I have tried this but I have a small problem and I don't know if I can explain it. The part is cut from a piece of 1- 1/2 inch stock...
... and I don't know if I can explain it. The part is cut from a piece of 1- 1/2 inch stock and the column center goes down to about .8 at the smallest point....
Hi Gang, I suspect this question has been asked numerous times, so forgive me for once again asking. I am looking at both a stepper motor based and servo motor...
Hi everybody I´m from Baja Califonia, Mexico. I´m new in this business. I want to now how can I get Suppliers and Customers for my new micro- enterprise. I...
... Yes, this has been dicsussed at least once before :-) It is about like a discussion of the preference between blondes and redheads- damn few facts and a...
Hi Joe, If you're comparing buying all new, then the price is probably worth it! If, on the other hand, you were to get the steppers off Ebay, build your own...
... based ... servos ... Joe, I'm probably with Ron on this one, and it's a little tough for me to say this. You see, I design control systems (like servos)...
Can I upgrade a 5400 with DRO to CNC and have both DRO and CNC? Is this better than CNC alone or even worth doing at all? I am new to machining and looking to...
I'm sure you can. I did it to my 2000 and it works great. You just need to have double ended steppers and you'll *have* to have the hand wheels on 'em since...
Hi I purchased the Sherline CNC package together with a CNC ready rotary table. Initially I had problems with the Z axis and the rotary table. After playing...
Alas, so far as I know, no it can't. I theory it should be doable. But the DRO has no output the PC can use. At best you'd have to "Y" the DRO sensor cables...
Hi Andrew, Yes, you can mount the DRO's on the backside of the steppers. Don't remember where I saw it. Probably on the Sherline website. With CNC, you don't...
Hi Ron, Try some simple, known moves to check out the rotary table. I was going to suggest that maybe it's binding? The motor may need to be shifted slightly...
Hi Andrew, Jeff, I don't know about reconciliation, that would require the controller program to read the DROs. I was always going to put shaft encoders on my...
... Because you WILL!! have times when the steppers have lost position for some reason or other it may only be 1 or 2 thou. or it may be from a crash or broken...
... Yes, Sherline's web site has info. That's where I learned how. ... Not really. The DRO measures actual hand wheel rotation and the CNC calculates based...
Ron, Does the binding on the rotary table occur when you try and move in an x, a motion or a y,a motion (a being your rotary). ie x 2 a 90 on the same line. I...
Hi Alan I am fairly certain that the table and motor are OK. When they are connected to the Y axis they work fine (apart from the scaling of course) with no...
Hi Dave All my comments at the moment refer to just the rotary table using the jog function in EMC. I suppose I should try a small program and see what happens...
Hi Ron, OK, I think I see it a little clearer now. If they work fine on one axis drive, but not another, then you have to look at the driver. Alan KM6VV...
