Sorry, that's a negative on both counts. Compatibility with Softools assembler syntax is fairly low on the priority list, I'm afraid. Regarding code...
Hello Gene Since I am new to cnc, I have the following questions for you. If you need feed back what is wrong with using linear scales for straight forward...
I do have one other related question. According to a couple of internet sources, the 1N752 zener is a 5.6 volt zener. Should this not be a 12 volt zener in...
Hi I am almost ready to try my stepper and the Gecko. Can I get away with no resistor if the motor is not attached to a load. Sorry for the newbie question. I...
Barry, The resistor is not necessary if the motor is not attached. Just make sure you place one on the drive before you hook up a motor. Bob Campbell ...
Hi Mariss, I just joined the group and hope to learn and contribute. I am doing some research on the phenomenon of de-magnetism of the rotor and stator when we...
For 30 days, starting Nov 15 until Dec 15, we are going to have a "customer appreciation month" G201s / G320s will go for $99. G210s / G340s will be $129. OEM...
Thank you, Mariss! I appreciate it...though you are appreciating US! This may be able to allow me to expand. I'll have to hint around my wife for some early...
Hi Mariss, I have a few different motors of unknown origin. Basically all I know about them is the supply voltage. Are there some basic rules of thumb to...
... These are the hardest to do. Peak torque is usually limited by the magnets. And it is impossible to determine at what point they will begin to lose ...
I am looking for stepper motors new or used, but in good condition. Does anyone have 2 steppers 200 step./rev.,single shaft(but double shaft will be...
I have a need to retrofit an existing G201 stepper system to shut down the Geckos (so the motors can spin more freely). Can I parallel the 4 DISABLE inputs...
Steven, If I remember correctly, Mariss told us that the disable was there for a specific customer. He recommended that we not use it. Optical Isolation is...
Steve, You cannot parallel the DISABLE inputs. It is a CMOS input that will be damaged if pulled a diode-drop (0.6V) below ground. This is almost certain to...
Thanks for the reply! I spent some time searching, but did not find the post I'm thinking of. I seem to remember him saying that the best way to stop a...
It might be easier to "float" the heatsink on some insulating standoffs. But I wouldn't really worry about the common power supply if I were you. If you were...
Thanks Jon, I have been playing with the numbers and here is what I get for my treadmill motors: 1500RPM @ 30V Kv = (30/1500) * 1000 = 20V/1000RPM Kt = 1.351 *...
Please, this is so unecessary. A properly wired control box should have its ground at the motor power supply ground potential, not at PC ground! If you note,...
... Agreed. I am trying to keep these two grounds separate. ... I've found that keeping the PC ground separate is not as easy as it would appear at first... ...
... Parallel port grounds are pins 18-25, there should be no connection from any of them to the shell. If the screen in the cable is connected to the shell, it...
Good day all, I remember quite some time ago a circuit was posted to buffer the printer port step/dir pins, it stemmed from a problem someone was having trying...
You are probably right that the cable shield SHOULD BE connected to the shell at only one end, Steve, but any PC cables I have opened up have had the ground...
... <snip> ... The screen of the cable is not connected to pins 18-25 _in the cable_, but it is connected _in the computer_. Actully, connected in the ...
... Easy to fix, cut the shield wire at one end, or make your own cables ;) ... Again - fixed as above, apart from the fact that the Earth wire in most PC...
... Because of FCC radio emissions requirements, all cables sold for PCs will be shielded, including the connector shells at both ends. So, the metal shells ...
