Driver problem — I’ve just installed a 5x7135 driver (bought months ago) set up with Guppydrv
but it’s got next mode memory on all of its settings.
Any guess what I’ve done wrong here? Could I have grounded something with the retaining ring?
It’s running a PC amber emitter that also came from Mtn.
Oh, and the turbo timer drops down to moonlight, not to 50 percent.
Is there a way to cancel the turbo timer completely?
EDIT nevermind, found how to cancel turbo timer by setting to 4 seconds or less (info is on the page for the larger diameter driver)
And I found a thread about the next mode memory problem at: Help! - MTN-20DD driver with guppydrv always starting in next mode - #12 by hank - Flashlight Modding and DIY Parts - BudgetLightForum.com

Hi, RMM. Any idea when you might have Shockli 5500 mAh 26650’s back in stock? Thanks…

Richard is now selling e-switch drivers with the Emisar D4 UI v2.
It’s available now on his website in various sizes from 15mm on up.
This is great news for all modders who love the v2 firmware in the D4 and want to put it in their other e-switch lights.

If turbo timer is stepping down to anything less than 50% there is a problem. To go any lower than 50% the driver thinks the input voltage is low.

Richard, is this the same driver that came with the D4 v1? I have a v1 and I’d like to change to v2 if possible. I don’t mind getting the same driver with v2 firmware and replace it.

No. It is the MTN driver with the same firmware, not the D4 driver. You'd be better off just reflashing the existing driver.

Regarding the MTN Quad and Emisar D4 flashlight:
You can swap the MCPCBs directly, with NO SPACER required. I had read some comments stating that a spacer is necessary, but doing the measurements and actually building some lights with the MTN Quad MCPCB it works fine without any extra spacer needed.
Could I put 4 XP-E2 Green emitters on your board and run em on the FET or would I have to reduce direct drive through PWM to keep from smoking the emitters like I did the Lee Filter I tried?
Maybe use the 18350 tube and a lesser cell to keep max current in check?

The ‘next mode memory’ problem I have is probably a bad capacitor or two, as people described here:
I can't help too much - don't have that particular one and there's no pics here or on the MtnE site. It should have a cap on the board for OFF time memory, and seems like that functionality is not working. If the firmware thinks the cap is always almost fully charged, it will always do the next mode. So, this is a possible cause of this behavior (cap is not functioning correctly due to possible bad solder joint or bad cap).
The OTC (OFF time cap) should be the smaller of the 2 caps - one end of…
and here:
I had this problem once. One of my capacitors (unsure which one) was not charging and discharging properly. I bought replacements for both C1 and the offtime capacitor, installed them, and my problem was solved. Try re-flowing the capacitors, and if that doesn’t work, try replacing them.
Time for me to learn how to solder itty bitty things.

I must be blind, do not see them under FET or linear drivers…

It can't be the capacitor. Maybe we flashed it with the wrong firmware or something because there is not OTC on that 15mm 7135 board, so the capacitor will not affect the memory.

It is a firmware option for the FET+7135 drivers---not a completely separate driver.

Bummer, I need a couple of side e-switch drivers and had hope for a good driver with good firmware to replace a couple of factory drivers.

Did I say 15? It’s 17mm

And they are available. Just select the correct diameter of driver from the list of FET+7135 drivers, then use the dropdown menu to select D4 v2 UI.
Hi Richard, what turbo timer option should I choose on the 17mm fet +1 driver with the D4 firmware? I wish to have the same configurable temperature step down as the D4.
Thanks

I don’t think the D4 ui has a turbo stepdown, so you can just ignore that menu. At least that’s what I did with my order.

Just ignore it. It is going to be the same firmware regardless of what you select, like Bistro/guppydrv/moppydrv/Crescendo.
