Hi all. During the time i'm using TurboCNC i've found an interesting problem: the linear interpolation goes approximately 1.5 times faster then the circular...
Hello, I'm trying to convert the control program on my 3 axis mill from CNCPRO to Turbocnc v 4.01 and am running the latest Freedos OS v 1.0. The mill uses...
Denis, Sounds like you have a configuration problem! Pin 2 is a data pin and "usually" is used for a step or direction pin output. Also, if you are getting a...
Dennis, I'm running both programs (usually on different mills). Switching one mill to TCNC was an exercise in reading the fine print twice ;-). The two ...
Hi Jeff, I checked the configure I/O and fixed the pin 2 contention and saved the .ini config file. Thanks for that tip, I might have forgot to save the state....
I'm not Jeff, BUT if you have HomeAsLimit set, then DO NOT setup limit switches. It won't work! (don't ask how I know) If you want to use the home as limit...
Dennis, Glad that I could be of some help. I don't run ANY switches but do recall reading that the config is almost counter intuitive ;-) Until some one with...
Hi Jeff, sorry, I hit the wrong keys and sent off a botched email. When I try to run a part file I still get a 'limit switch is active' message. Nothing is...
... I'm curious - is this Windows 9x or Windows XP? Also, how are you handling the driver for the real-time I/O? -- Jerry Jankura Strongsville, Ohio So many...
I have 6 Anilam Crusader M lathes. The controls are shot and I was thinking about using TurboCNC with the existing servo motors and Servo Amps. I don't see...
Denis, If nothing is connected to the printer port make sure to turn off E Stop in the IO. My mill faults if I have the driver box turned off; I'm too lazy to...
Hi Jeff, I configured the each switch to perform 2 functions in the config I/O menu. Will try to straighten it out tomorrow. cheers, Denis ... recall ... ...
Hi Art, yeah I setup the config to use the limit switch as the home swithces and tried to set each switch for both limit and home functions in conig I/O, so...
1. Program runs both on win9x and XP. 2. If I understood wright, you are asking about the realtime problem. I didn't write lpt driver, there is a good one in...
If the servo drives are OK you could use step/direction converters. These are available from Rutex <www.rutex.com> and Skyko <www.skyko.com>. However the...
Denis, Sounds like you are on a roll now and it won't be long before your making chips. The action of home switches in TurboCNC is to move the axis until the ...
Hello, Just curious ... How many axis??? Eric ... Indiana95@... __________________________________________________ Do You Yahoo!? En finir avec le spam?...
I don't know specifically what encoders you have but I did come across information on how to use the encoders that have many more outputs just by selecting the...
Hi Art, ... I disabled all 3 limit switch and 8 home switch assignment in the configuration, saved the *.ini file and was able to air cut a part file. But how...
Hi Jeff, thanks for the Estop tip. I have disabled the Emergency Stop ( item 18/40 ) in the Configure I/O menu. Is that supposed to be used for the limit...
(no, I haven't messed with servo motors or their drivers, just steppers, but...) I was under the impression that a servo motor was controlled by the ...
Not all servo drivers take step/direction. Virtually all older drives use a control voltage, usually in the range -10V to +10V. 0V-stationary, +10V = full...
Denis, Totally separate from the limit switches. I mentioned it because if I try to run a program with the controller off :-) I get an E Stop message on the...
Denis, Setup your HOME switches in the configuration file. THEN set HomeAsLimit and you are done! DO NOT enable the limit switches or it will not work. To...
... <thardyguitars@...> ... Servo ... I'm sorry that what I'm about to post is not TCNC related... But for your conversion I think you would get a perfect fit...
Back to the microcontrollers logic... I've heard about the "method of digital differential converters", both the linear anc circular interpolation are built...
Sir, Are you referring to DDA's, digital differential analysers? I have made a CNC controller where I use something similar to that. My approach is that...
I am getting that runtime error as well. I found that when decreasing feed speed via the < key when doing G02-G03 moves, it crashes after that present line...
