Tim, on further investigation I think you are right, there's a light on the main pcb that goes out when the link to the back of the XLR pcb is disconnected, that light has always been on so there has been some sort of connection happening there I think. I have now managed to get the power light on the remote panel to work, it was a dodgy pin connector on that circuit from the main PCB to the small PCB at the back of the remote connection. So now I can get the remote power led to light up but I still get the same problem of it firing as soon as it reaches temperature, it does this with or without the remote so perhaps its not that circuit that is my problem. I have adjusted the variable dials on the PCB (one for 'pump' one for 'sensor') and they are making a difference. The sensor dial can be used to make the machine fire, I guess by changing the ready to fire threshold, and then it is firing as soon as it reaches whatever that temperature it. So I need to find out what is bypassing everything and just allowing it to do that. It is ok inside, no signs of any moisture, its all pretty basic wiring apart from the PCB, I guess theres maybe some sort of brain chip that has fried so that instead of thinking about whether it wants to fire when it receives a signal it now just does it? So frustrating as its a really good machine, I'm even tempted to just keep it and crudely just turn it on and off to operate if I have to

I think the machine is heating up without the remote or DMX being connected, so what you are saying is there must be a short somewhere? Could this be on the board? The wiring seems pretty good but I havent looked much further than just looking for bad looking connections. There are some jumpers on the PCB near to the DMX switches, could it be possible these have been set wrong? It's definitely heating and it definitely isn't lighting up on the remote so I guess I should look further for a short, I just cant see any areas that might be prime suspects (in the back panel area at least) Thanks for the quick reply that was brilliant

Hi all, relatively new to the forum and in need of some advice please I have a ZR33 that doesnt have the remote light coming on. It will heat up to the point that it is ready and then start churning out smoke non stop until it is disconnected at the mains. I have had the cover off and the fuse for the remote seems ok but it doesnt seem to be getting power to it. I havent tried it on DMX as yet. Is the machine switching to full output nonstop once it has warmed up normal behaviour for a machine without DMX or remote control? Does anybody know why the machine would want to output as soon as it is ready? Thanks in advance for any help, pretty frustrated here!
