K-1 mII, TT350p, wireless manual mode with another TT350p

Hi guys. I sent this support email to Godox yesterday, and while I wait on a reply, I thought maybe you guys could have a go at the problem I'm having. See below...

I have tested both flash units in MASTER mode, and in SLAVE mode, and the following is true.

1. The master can trigger the slave using the TEST button in MANUAL mode.
2. The master will trigger the slave from the K-1 mII hot shoe in TTL mode and in MULTI mode.
3. The master will NOT trigger the slave when used on the camera's hot-shoe in MANUAL mode. Since I require manual flash, it is important to have this function working.

I have only one Godox flash so haven't played with their set-up, but it could be that you need Godox transmitters like X2T or X-Pro for full functionality?

If you don't require TTL, than you can buy the dumb optical receivers and use almost ANY flash as slave. Note: It won't do HSS, and the master flash needs to be visible to slave unit.

If you don't need TTL and HSS then another option is to to buy the FlashQ transmitter and receivers. They have plenty of benefits: 1) smallest and lightest; 2) can be used on any camera system you have; 3) any flash can be used (for example, I use the ones that recycle faster...doesn't matter which manufacturer or system--you can use one Nikon flash and one Samsung flash with your Pentax camera :-D); 4) set-up is radio-controlled, so you don't need to worry about the master flash being visible to slave; 5) you won't have a flash On-Camera.

Hope it helps.

I have the fuji version of the TT350. I use with my k-1 in Manual, and sync-limited. I have a variety of other Godox units.

Putting a Godox TT600 on the K-1 hotshoe successfully triggers the TT350.  The 350 was set to S1, and the hotshoe-mounted TT600 set to "M", though I'm not sure that was even necessary.  Perhaps you can play around the admittedly confusing settings and have another go at it.  Obviously, you can't control the slave flash in this fashion, just fire it.

Thanks for your comments.  The TT350P has the wireless function of the Godox transmitters built in, and should be communicating with the slave unit. In fact it *IS* communicating with the slave unit in every single mode except the one I want it for... Manual flash.  TTL works, and so does MULTI mode.  Just not M.  Even the test button sets off the slave.

The TT350 also can be controlled in 'dumb mode,' as you put it, which may be useful as a last resort.

Thanks for your reply!  If you are using the TT350 in S1, then it was set as to 'dumb mode,' as the previous poster put it, and was acting as an optical slave.  I think I still have this function, although I haven't tested it yet, but wireless manual definitely is not working.

Thanks!

Did you by any chance have the shutter speed above 1/200th sec, i think above that the camera refuses to fire a manual flash or a flash in manual mode.

Thanks for your response, MM.  Good suggestion, however I'm pretty sure I kept the shutter at 1/125 for the test.  Maybe I should put it even slower just in case.

Thanks

Ok. I thought their flashes can act as radio-controlled receivers OR optical slave/master units. Actually, now I wonder what is the purpose of X2T when their flashes can radio-controll other flashes?

, and should be communicating with the slave unit. In fact it *IS* communicating with the slave unit in every single mode except the one I want it for

Try to place the other flash in a different room, and confirm whether it is being controlled via radio?

Lastly, try to reset everything (both flashes) and see if the problem persists?

Just read more on Godox system and you are correct: TT350 has transceiver function. As for my question, several Godox flashes (V850II, V860II, TT600) do not support P-TTL directly, so you need their own trigger on camera to “translate” the TTL message from the camera to their flashes. Neat! And man their recycling times are amazing on VI, V850II, and V850—just 1.5 seconds---time to dump my Pentax 360/540 flashes that take 6 seconds..

Based on the description given here , TT350 can radio-control some other flashes/strobes but NOT another TT350.

Thanks for posting this, Massao.

Hello JCDoss

I don't have this flashes, but Massao posted a link to the manual.

Point 8 in the manual: You use the group A, but can it be that you must use on the master flash the mode button until you set the slave to on ? In the group A,B and C you can set on the master the slaves to on/off. Now point 8 describe the multi flash use, but maybe your point 7 use have also such an on off setting for your slave via the master

Best regards. KPM2

Hi, KPM2.  Sorry for the delay, I don't check this forum very often.

I did see that Massao posted the manual, and I already had a copy that I reviewed before posting.

I'm not sure I understood your comments.

Point 8 is for MULTI flash, or strobe, and it actually works fine in that mode.

Point 7 is for Manual wireless flash, and following those instructions I can't get it to work.

I am still waiting on a reply from Godox.

I did finally try optical mode (slave flash triggered by main on-camera flash, not radio signal), and that works just fine.  So I suppose the problem is solved, but I'd rather have a fully functioning set of flashes.

The TT350 is a fantastic flash even without wireless.  Recycle times are very fast, the unit is versatile and provides good power for indoor and close-up work, and is pocketable.  I highly recommend the flash, esp at the price point, even though I'm having trouble with mine.

I thought that, when you are in the wireless mode but the flashs in it's manual mode, you can still set via the groups the settings on your slave flash at the main flash, like for example that you can set on the main flash the slave flash to off or on, like the manual described it....but only at point 8 for the MULTI flash use.

Maybe it is a software bug, because using the test button seems to work as you wrote.

best regards KPM2

Thanks again!  Yes I think I understand this time and you are right.  I can control the flash output on the slave from the master flash.  It all works perfectly except for one thing:  neither flash will go off when set to Manual.  Multi, TTL, and the test button, and control features all work as advertised otherwise.  It could be a bug, or it could be something about the K-1 mII.  I don't think the TT350 is labeled to work on a mark II, so maybe Pentax changed something?

Thanks again for your help!

Maybe update the firmware on flashes, if its never done. Link
