BTT UPS #1732

sinole1987 · 2021-03-14T22:58:17Z

I have the btt ups, and i see that there is a ups feature, i wanted to know if i should connect the panic pin to tft screen as well for the signal or main board will send to signal to tft? and if I should connect to screen, which pin should I connect to?

Refer to this #1458

Lots of testing with the UPS but it seems like it only works properly through Marlin.

sinole1987 in the BIGTREETECH-MINI-UPS-V2.0 repository you ask about the Relay v1.2. Which device are you finally using or is it about both?

sinole1987 · 2021-03-15T23:16:00Z

I bought both of those moduls, I though I can build my printer with automatic shutdown and power fail protection, which to be honest power fail is not that necessary. But it wasn't to hard to add until TFT screen came into picture. I didn't know that TFT software is so under developed. Relay works great, since it just need to hear M80 from board. the ups on the other hand. if it doesn't work right. it can even corrupt tft Firmware, which is kinda scary.

can you tell me the file in which pins mapped for tft program, because someone wrote program for connecting UPS to tft screen but I cant find to which pin they assigned the UPS.

Hello, BTT UPS needs to be connected to the motherboard and detected by Marlin in order to obtain the highest priority. Once the power is failed, some high-power loads such as hotbed and heating rod will be shut down immediately, so that the power in UPS can supply the stepper to move a longer distance.

First of all, you need to set the POWER_LOSS_RECOVERY function in Marlin, and then you need also to set some parameters on the touch screen config.ini. The most important thing is to enable start_gcode and add M75 if printing from TFT SD or TFT Udisk

In addition, if it is printed OnBoardSD and the TFT is working in touch mode, after power failure and restart, the TFT can not detect the POWER_LOSS_RECOVERY information of Marlin by Serial data, so it needs to manually send M1000 S1 gcode in the Terminal menu to resume printing

You can get some information in here #890 (comment)

Im going to try that. thank you

worked great thank you.

How have you solved the need to send M1000 S1?

sinole1987 · 2021-03-30T07:24:28Z

It just sends it to main board. and it interrupts the host. I had no issue there. but it is very important to set start G code exactly as was recommended by BTT post so the host knows where it is. I tested a USB print and even that one worked.

sinole1987 · 2021-03-30T07:38:55Z

Although, there is a hardware issue with UPS module that I hope BTT solves in revision 2. It seems that power delivery and power draw is not very smooth. when you turn of the printer it turns of slowly, screen flashes and stuff. and when you turn it back on capacitor are empty. they draw so much power that printer doesn't boot. you have switch it on and off again. I will post this on respective page later. maybe I should use lower AWG wire to power the UPS. im using same AWG 14 that i run to the mainbaord.

oldman4U · 2021-03-30T08:28:57Z

As far as I understand all the TFT does is to let Marlin know that a print has started and the resume after failure which is independent of the UPS device. sinole1987 ***@***.***> schrieb am Di. 30. März 2021 um 09:39:

well, I connected the ups to the main board, and it is sending m1000 to marlin. perfectly interrupts any print on tft and raise the nozzle.

oldman4U · 2021-03-30T11:30:15Z

Once the power is back the TFT also works? BTT suggested to send M1000 using Terminal. sinole1987 ***@***.***> schrieb am Di. 30. März 2021 um 11:55:

yes, once the power is back, I just go to menu and select the media I was printing from, then it will ask if I want to continue print that was interrupted. If you confirm it will heat up printer, homes, purges and continues printing. but it will dump a little filament on the print again for some reason just like m600 used to, its much less though. I also activated these two lines in marlin:
Marlin/src/feature/powerloss.h
#define SAVE_EACH_CMD_MODE
#define SAVE_INFO_INTERVAL_MS 0

PLR is not working in marlin 2.0.7.2 . I really don't see myself going back and setting up for marlin 2.0.6. but i know it works. As for marlin bugfix, I couldn't get it to work with TFT. X and Y didn't home. and everytime i pressed home X or Y on TFT nozzel came down full force and smashed into the bed.

ahmetbozaci · 2021-04-17T22:28:47Z

I am not sure problem is marlin version. Because ı use powerloss before upgrade tft and ı am using last version of marlin.

sinole1987 · 2021-04-17T23:16:47Z

I know for a fact many other people had problem using PLR in marlin 2.0.7.2, which is that last version. there are some open tickets on marlin GitHub. https://github.com/MarlinFirmware/Marlin/issues/19602

oldman4U · 2021-04-28T15:12:16Z

Most likely you have seen the https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware.git which has a minor bug fix for PLR.

Check if it solves your problem
