I have a trotec with a synrad firestar t60, It was too expensive to regas it and I bought a reci tube 90w (from china) I conected but now is not working properly, it start engraving any logo with very low power and end also with very low power, if the head moves fast, the problems gets worst.
A friend tell me that the problem is with ttl signal has low, the computer is sending low miliampers tha the new power supply doesnt work good, but this option is difficult to test it.
If anyone has an idea of solving or maching the trotec system to a glass laser, i will apreciate very much your help.
thanks
david
