I Measured the sense resistors in and out of circuit and they showered a higher resistance of 2ohms and not 1.5 ohms so swap them as a just in case measure as for the 3692, I'm not to sure as the oscilloscope I have to hand dose not have any probes, unless its something I can measure with a multi-meter I cant tell if this is the fault. is there any faults that happen as standard with the mac 500/00 pcb ?

Hope these help, please excuse the bad soldering only had a TS80 to try and get the resistors swapped out https://ibb.co/nsptYc7 https://ibb.co/4RhL39J https://ibb.co/fdw5Nyz https://ibb.co/BzHNtvB

Hi Rob yes have swapped over a working PCB from another mac 500 & mac 600 and all motors on both fixtures are working 100%

Hi All Hoping you can help I have a pair of Main PCBs one for a MAC 500 and One for a MAC 600 E-NT both have a slight issue mac 500 Pan Driver is an issue it pans for 1 second then starts to judder and is very hard to move by hand ( have swapped looms and driver chips with tilt, at different times and fault stays with driver socket. Motors all check good, have replaced all the 1.5Ohm resistors for the Pan Driver socket and had no change) Mac 600 Tilt Driver issue driver tries to move the tile motors but is unable to and it Very weak to hand ( Had done fault finding the same way as above fault stays with the socket again and the motors both work perfectly on the Pan driver chip) any knowledge you have about these PCB would be appreciated and of great help Ben
