750 H/S plus

I'm not aware of any code to align the blade to home if that's what you are talking about and I am only familiar with the previous series of Gerber plotters before they added the + feature ... so take these instruction with a grain of salt. The easiest way to do this is:

• Unplug the machine and remove the end covers
• Turn the toolhead to locate which parts are moving and follow it back to a collar clamp
• Plug in the machine and turn it on. It will rotate the blade and toolhead to it's home position.
• Using a hex wrench, loosen the collar clamp. Rotate the toolhead to its home position, which is precisely where it would be to make a clean cut on the X axis and with the vinyl moving through the plotter from feed in to feed out.
• If you lower the toolhead to where the blade will cut vinyl and manually turn the drum, the blade will very quickly find its home position.
• Tighten the collar clamp.
• Run a test cut to see if it works okay. If so, unplug and replace the covers.

Things to check before you go through these steps:

Is your theta belt missing any of its gears or very loose? The theta belt is what turns the tool head. If this belt has missing teeth, order a replacement from your GSP dealer. Once you have installed it, you will then need to set the home position as listed above.

Is your plotter clean and has it been lubricated? Lack of lubrication is the most common cause of malfunctions with all the older Gerber plotters. There is a standard maintenance procedure in all the books I've ever gotten with GSP plotters. The main thing is to wipe all shiny shafts with light oil and to add one drop every six months to the bronze oilite bearing inside the toolhead.

 

My old HS15 plus had the same problem but my clamp was broken. I don't remember if I downloaded the instruction from Gerber's site or they sent it to me but it was available from them and quite easy to fix.

 

This might help even though it's a different model. Go to page 56 for a step by step Theta axis adjustment.

 

Theta belt Sprint 2B /Any Helpful Hints?

First time to post . . .

Have a Gerber Sprint 2B.
Any helpful hints when replacing the worn out theata belt.
Seems to be a snug fitting belt. Had no issues removing, but
it looks like it could be a little harder putting a new one back on.

Thanks,
Kevin
