Just wondering how much trouble it would be to replace my current Sherline motors with something a little more beefy. I noticed Digitkey has nema 23 MK motors...
Hello i am looking for a complete mini machine shop in good condition that includes a CNC MIll and lathe as well as cnc rotary axis and as many acessories and...
I don't use EMC and thus can't address your question directly. However in my experience the Sherline steppers are more than adequate. Stalling is often...
... I would change the controller, not the motors. The Sherline control is about the worst possible design of a stepper motor controller, firmly based on about...
For what it's worth, my sherline mill has no problems with losing steps (running Mach 3... previously ran EMC) when my cut depth and feeds are set properly for...
A servo will NOT prevent you from losing position if you overload it, but it will tell you that you have. Servo motors tend to have a flatter torque curve so...
A closed-loop servo based system WILL get to the desired position...just not when the g-code expected it to. I agree with you comment on the steppers being...
We have to be really careful with terminology as it is easy to let the buzz words get in the way of understanding what is really happening. I’m not wanting...
Paul. I have a new Sherline 2000 series mill and a new Sherline 4400 lathe. New Sherline computer with driver with Linux emc2 installed a Sherline rotary table...
Hi I am trying to turn my mill into a 3D printer. I only have windows right now because I am using my woman's computer. I suck at this code stuff and need help...
... That, unfortunately, doesn't work. The Sherline motor control box communicates with the PC through the parallel port. 3D printers, at least those in the...
... Those converters are actually printer port(not parallel port) to USB converters-and while I have seen ones that make a printer port out of a PC USB port, I...
Hi Jeff, I have a cnc Taig mill and I found that I get better and smoother movements from 1.24 NM motors than with 1.8 NM, I don't do a lot of rapids but I'd...
A.G., The 1.24 NM (~166 oz-in) is a perfect size for Taigs or Sherline's (with stock leadscrews). The lower inductance and lower inertia (rotating mass) work...
Hi Jeff, Thanks for confirming that I have got things right. I do in fact have a 1.8 NM motor on the Z axis but I have found that I constantly have to put up...
Try lowering your acceleration on the Z-axis by half (or set it to 4 in/s/s whichever is lower). The cheap import stepper drives are usually limited to 24V...
Hi Jeff, Will recheck the Acceleration setting as suggested. Many thanks for your help. Regards, A.G From: Jeffrey Birt Sent: Monday, October 22, 2012 6:11 PM ...
Peter - I've had this Geko 540 kit for a while now, and I can't get it to do anything. So far it's an expensive paperweight. I know it has to be something I'm...
OK, I found the cable pinout for both the Mach3 and the Gecko 540. There's just one problem: The Gecko pinout for the DB25 connector refers to "X-Axis Step",...
Hi Bert, The X++,X--, Xhome are Mach3 inputs for switches. In Mach3 configuration there is an adjacent tab that has the Mach3 motor outputs tab. There you will...
The Gecko has two input lines per axis. The direction line is taken either high or low, and generally left there (for the duration of a move in one direction)....
I've been having a bit of a problem with my Sherline 2000 mill. I've noticed that it's been consistently over milling whereas the X and Y cuts have been where...
Today I started having issues with my lathe. It has functioned perfectly to this point allowing me to run simple programs. Today I install a tft monitor and...
