MikeMart Posted October 22, 2023 Share Posted October 22, 2023 Hi, as on my TT layout I'm using double slip from Tillig (which has no springs) I bought some seep PM4 point motors. But for some reason it won't work. It fires, moves for fractions of millimetre, but not enough to move to other coil. Other seep motors without latching mechanism works fine, so there is no issue with HM6010. I remember reading earlier that HM6010 has built in CDU, but can it be not powerful enough? If so, is it possible to add additional one somewhere before motor? (Forgive my ignorance, wiring and electricity in general is still somehow dark magic for me) Link to comment Share on other sites More sharing options...
LTSR_NSE Posted October 22, 2023 Share Posted October 22, 2023 Have you tested the SEEP motors (powered by HM6010) without them physically installed and attached to the point? (To verify they are in sound working condition.)If they work uninstalled & unattached, but not once they are, the most likely cause is an incorrect/problematic installation - resulting in them being physically prevented from moving.If following further testing CDU is determined to be too weak: the ‘C’ (common) pin of ports 1-3 on the HM6010 can be combined to increase the strength/effectiveness of the in-built CDU - since they share an internal circuit.However it is critical to keep port 4 entirely separate, since it uses a completely separate internal circuit & you would cause damage to the HM6010 by bridging these circuits.

MikeMart Posted October 22, 2023 Author Share Posted October 22, 2023 Yes! Combining common pins made a difference! Thanks! Although interestingly it worked only on one of the motors, the other stops halfway. Of course I can buy new one and try again, but I wonder, could some lubricant help?

MikeMart Posted October 23, 2023 Author Share Posted October 23, 2023 Just for future references if anyone has similar problem even after combining common: after some wiggling with that little spring both motors work correctly! Problem solved! And once again thanks LT&SR_NSE! Link to comment Share on other sites More sharing options...
