Can you tell me how to distinguish between them? I recently bought a second GSM2. With it I've got two FlexJet heads (dismounted). The serial number of both heads starts with FJ7P, so I assume they are of FJ7 type? The issue is - it seems that the he

Whether the Juki is a great machine or not is irrelevant as we just can't justify the "starting from" price of $87k (€58k). So, thanks for the suggestion, but we're trying to keep this under $20k and given that sort of budget we could either buy a cr

Tom: Once again - why are you using solvent based conformal coating. 1B31 is OK as a CC but it contains Toluene and MEK!! It is only 35% solids which means you are trying to get rid of 65% solvent. If you must use it due to customers requirement then

I have a number of computer parts with faulty VRAM. I have two high-end video cards and a laptop motherboard, each worth over US$100, and some other parts worth less. They all exhibit symptoms typical of faulty VRAM; that is, they display multicolore

I have moved golden boards from chains to mesh as I got tired of fishing t-couples under the chain rail. I saw a 3-5 deg. decrease on top-side parts peak temp. (all t-couples were on top side). I had to bump zones 6 and 7 a few degrees to make up f

Yes, it's powered up. We use a simple power supply that connects directly to the drive. It spins up fine. I belive my problem is with Windows not recognizing the old type of drive correctly. It does recognize it as a mass storage device (the drivers
