\r\n Try the LM317AVT or keep the supply voltage 35V or less. You can also place a zener diode inplace of r26 to increase a LM317T\'s 35V by the value of the zener.
\r\nThe BZW04-048RL could be eliminated by using a MOSFET whose breakdown voltage is more than double your motor power supply voltage. i.e. if you are using 40V PS a 100V logic level mosfet should be ok.\r\n

\r\n If you can get the LM317AVT that would be the best choice, second would be a 1n3734 or 1n3735 (Zener). Make sure the bar end of the zener is the one that connects to the incomming power supply connection.\r\n

\r\nR u tellin me to use the zener in place of r26? what about the MOSFET let them be the same? U were talking about changing the FETs is that not required?

\r\n Hi Phil
\r\n
\r\nHow r U,
\r\n
\r\nI have got the following, IRFZ44N\'s, ordered BZW\'s from mouser and got it already, have taken all half watt resistors including the ones on the optoisolated breakout board(i hope its not a problem) got a 22000 MFD 63v nippon electrlytic capacitor for the PS,
\r\n
\r\nThe motor is rated at 3.35A , one set of winding returs 0.9 ohm and another set 1.5 ohm, i have three motors and all return the same resistance values. Will this be a problem.
\r\n
\r\nI have calculated the V ref for my motors with R11, 12, 24 in place as 3.35*0.33=1.1055V, u think its correct,
\r\n
\r\nwhat shunt resistance should my PS have?
\r\n
\r\nFor the optoisolater ic using H11A817, after studying the motor driver circuit i have come to a conclusion that there are no pull up resistors on the motor driver and i can have the 3.3k pullups on the opto isolator board,
\r\n
\r\nI have not understood how to connect the EStop to the motor drivers, can u help...
\r\n
\r\nthanks in advance

\r\n Hi contactirfu,
\r\n Me I\'m confused....I have a hard time sorting out who has which board and what we have been through. I get questions on various threads, emails, and on my BB. One of the reasons I created my on BB http://www.pminmo.com/phpBB/ was to help me pocket questions about specific boards so when I reviewed the thread, I know going in what the board is going in. Also that others headed down similar paths could review the thread of the board they were interested in. If you would, how about doing a cut and paste of your previous posts to put them together in the right thread on my BB. Would be a big help. Thanks, Phil\r\n

\r\n
\r\nBasicly i would think that if there is a pulsing on the board logic when i move the Axes on the computer it should work maybe there isent enough current somthing like that HELP !! please
\r\n
\r\n
\r\nthe power supply i am using is 12v 8amp running at about 11.5v 7.5amp

\r\n Hi all. I am about to start building driver boards and the BOB while I assemble all the components to build mysef a JGRO CNC router. I have a couple of questions regarding the Open Source L297-8 bipolar driver boards you guys have done a fantastic job of developing for us DIY\'ers.
\r\n
\r\n1. In the documentation for the L297-8 drivers PMinMO mentions the fact that we can use LM138/338\'s instead of the LM317 voltage regulators. My question is, is the LM338K a drop-in replacement for the LM317? (with obvious regard for the BCE configuration, and the maximum current rating of the L298\'s )
\r\n
\r\n2. The datasheet for the LM-series mentions that the usable voltage range is not from 0V to the rated maximum, but rather that the maximum rated voltage may not be exceeded between the source and load pins on the regulator. This suggests that as long as we are not regulating down by more than say the 32V allowable range of the LM338K, we can use higher voltages through the regulator. My question is, is this possible given the other components in the system such as the L297/8\'s? It would make my 24V salvaged steppers useful for my project.
\r\n
\r\nAny help would be appreciated. I am not an electronics guru but have been building other people\'s designs for years, so while I know how to put \'em together, i\'m not skilled enough to make changes to them to suit my needs.
\r\n

\r\nAs far as I know the LM138..LM338 are only available in TO-3 packages. The pcb for the L297-8, the LM317 is a TO-220. Two entirely different mechanical packages.\r\n

\r\n \r\n
\r\n
\r\n
\r\n
\r\nAnyhow, I too realise that the TO-3 package is vastly different to the TO-220 package, but apart from the obvious issues mounting a TO-3 with heatsink to the PCB, it is still an easy task to substitute the LM338K if it will work in the circuit.
\r\n
\r\nI\'ll try and find the relevant PDF when i\'m at work again in the morning.
\r\n
\r\nWayne
\r\n
\r\nEDIT: Oh bugger! I remembered where I read it, and it wasn\'t even a relevant PDF. It was in the datasheet from National Semiconductor! Clearly i\'m getting old! Quoted below. 
\r\n
\r\n\r\n
\r\n
\r\n
\r\n \r\n For applications requiring greater output current, see LM150
\r\nseries (3A) and LM138 series (5A) data sheets. For the negative
\r\ncomplement, see LM137 series data sheet.\r\n \r\n
\r\n
\r\n
\r\nFURTHER EDIT: In support of my other question, here is another quote regarding the fact that the max voltage handling capabilities of the LM317 refer to the differential between the input and output voltages, and not the maximum voltage above ground that the regulator can handle -
\r\n
\r\n\r\n
\r\n
\r\n
\r\n \r\n Besides replacing fixed regulators, the LM117 is useful in a
\r\nwide variety of other applications. Since the regulator is “floating”
\r\nand sees only the input-to-output differential voltage,
\r\nsupplies of several hundred volts can be regulated as long as
\r\nthe maximum input to output differential is not exceeded, i.e.,
\r\navoid short-circuiting the output.\r\n \r\n

\r\n
\r\n Both the 317 and 338 are floating regulators, so max input to them is the regulated output voltage plus the differential max. So for a LM317 that is configured as a 5V regulator, 45V is the max input voltage. (40V max differential). The 338 has a 35V max differential verses the 40V of the 317. Computing resistors is the same, except Iadj is slightly different.
\r\n
\r\nBTW you don\'t need to regulate the voltage for the motors, if your thinking motor current comes into play.\r\n

\r\n Thanks for the feedback PMinMO. I was thinking of using an LM338K instread of the LM317 to reduce the workload on the regulator at higher currents. By that I mean that if you run a device rated at 3A at 3A you are driving it hard and will have issues like a high average working temperature and shortened lifespan, whereas if you run a device rated at 5A at 3A you are more or less in the mid-band of the device\'s capabilities which should reduce the impact of temperature and lifespan.
\r\n
\r\nOver and above that, I would like to run my boards at 3A if possible to cater for a few higher torque motors I have scrounged.

\r\n
\r\n Again, the regulators in the circuit, as designed, DON\'T play in the motor current......... You don\'t need a 5A regulator for a less than a 100ma. If you look at what the LM317 runs, it\'s the 5V on the board. The incomming unregulated VDC (18V or more) is used for the H bridge of the motor in the L298.
\r\n
\r\nIf your thinking of regulating the supply voltage to the motors, don\'t, it\'s a waste and more times than not reduces performance.\r\n

\r\n Does anyone know why I would be able to run my Steppers with TB6600 Drivers and a DM542T Driver, but not with my gecko 201x driver on Mach 3? All I’m getting is stuttering or the motor only moving in one direction. When it’s energized with the driver, it is possible to turn the shaft manually easier than usual.

This Driver With the compatable BOB
Discrete Driver Boards
The Stepper is 12v 0.4a 6wire
the boards work as far as i can tell i have had turbo cnc running and was a ble to use the logic probe to get pulsing from pin3 on IC4 so i am guessing that it is all working i have now installed IRLZ44N in place of the IRF540N that i purchaced at the time. the motor will still not spin
i wired yellow and blue together
and red and brown together
grey and green to +12v
dose it matter what Wago they go into (x9-1 yellow red ect) i have tryed other combo's with no change. the motor moves if i rub one of the wires on to the -12v. I have no idea what else to try the mosfet's are all working as far as i can tell IC4 pin 1 high Wago X9-1 lo ect as per instructions, +5v working well
Basicly i would think that if there is a pulsing on the board logic when i move the Axes on the computer it should work maybe there isent enough current somthing like that HELP !! please
the power supply i am using is 12v 8amp running at about 11.5v 7.5amp
