Jon 5 x 1000 =5000. Assuming quadrature encoding, 5000 x 4 = 20,000. How do you acheive 40,000 counts/inch? Steve...
Thanks to Steve for his explanation of the difference between printer and CNC applications. It was, in short, that a CNC beats on the servo much harder than a...
... Right. I knew about the balls (I've got a set on the BP) but I didn't know how they gathered data from them. I know they are advertised to have a faster...
... Hmmm, you are quite right. It is 40,000 on the Z axis, with a 10 TPI ballscrew. As you say, it is 20,000 counts/inch on the X and Y with their 5 TPI...
... I don't know how the Newall can have a FASTER refresh than direct-reading optical encoders. Most can produce 100,000 quadrature counts per second with...
Right again, I think I'll just leave it up to people with just a bit more experience in this area I completely forgot about the limitations of the serial...
Being firstly an electronics kinda guy, and secondarily a machining person, for some years now I've been dreaming about a PCB milling machine, either building...
Comments: 1) Is the program erased? You do know that you can send the HDD off and have the disk data salvaged if it hasn’t been overwritten or formatted? I...
Alan, If I had the time to invest, I'd go for reverse engineering the RS-232 interface and command sequences. It's possible a Google search might even find...
I've decided to "roll my own" minimill cnc conversion rather than buy something already built to save some $$$. I will be using stepper motors. I am trying...
Thanks for the reply ! ... This is what I do for a living. It's gone. More to the point, so is the required dongle. ... It's not quite HPGL. It's close,...

... I'm leaning towards that, half because of the challenge, half (if the truth be told) because I'm feeling guilty about just how much I spent on a toy. ... ...

... Thanks for the reply. Unfortunately, I have too much invested in Protel in terms of time and money to look to anything new. Heck, I'm still working my way...

Yes DeskPCB is a good program. We have used it. Jim ... [Non-text portions of this message have been removed]...
... datas. There you get professional help. ... Thanks to for helping me out! Now I can be more specific. This cnc lathe of KITAMURA, model KNC-50 with FANUC...
... Roger, Dan, I've been very busy with work, I had to build my own automated microtome system as well as a lot of other stuff, I also recently picked up some...
Graham, I picked up an old HP 960 from the recycling center and it is close to a perfect fit for a 3D printer. It uses the old style HP cartridges with no...
... You are mixing apples and oranges here- the Xylotex is a driver board- think of it as the power amplifier to drive motors. The deskcnc is a signal...
Dear all, first let me say hi to all the members, kindly if any one can help me abount readind a pulse encoder that sends 2085 pulses per second square wave...
I own a T-TEch and the software is free. but it only runs the machine, it does not do the isolation routing from the file. The dongle costs $1,000 (list) and...
... Considder buying some parts and making others. the mill is easily capalbe of making many of the parts, but some parts are low enough cost to just buy the...
I and others have used the 'hobbycnc.com' controller with EMC and other software to drive stepper motors. It reduces expense, at the expense of having a...
... What rate is the C program reading the port? What port pins are you connecting this to? Did you check the voltage levels out of the encoder? It may...
... And, in most cases, they tell you "Oh, that control is obsolete, we don't support it any more. We can sell you a new control and find a retrofitter to...
... I think all is well, the spreading just seems to require that the roller goes at about the same speed as the gantry so it effectively acts like a non...
Ron, The way I read it, and reread it, it needs only power supplies 12VDC, and 5VDC, wires, and steppers??? What am I missing? The more I try to ferret out...
