From the original Synthetos forum (2011–2025)
A double fast (double speed) Spin/Dir flash LED indicates that a limit switch has been activated.
Do you have limit switches enabled?
Perhaps disable them and see if the behavior improves.
However, it sounds like you have no communication with tinyG whatsoever, so you won't be able to reset the parameters.
I haven't installed limit switches yet. I went ahead and filled out the product support request form.
I'm not sure if this might shed light on the problem I'm having, but the code below is what I see when I reconnect to chilipeppr. There are green checks next to every line before {"mt":""}. After that there are yellow checks and the buffer stops responding. I hope Synthetos will not burn me on this one. Even though I bought the board just over a month ago. I've yet to cut the first part using it.

{"ej":""}What you show is the CP start-up command sequence, which it uses to query tinyG for current state and status on initial connect.
I see no responses, sounds like you are sending but not receiving.
Spin/Dir flashing thru all this?
i have the same problem with mine. Turned it on and the spindir is contantly flashing
is there anything i can try while waiting?
Pig pile! Unfortunately, you are the second this morning and (at least) fourth in the past week to report this.
What you report may/may not be same as the thread you added on to.
Please start a new item, summarize what happened to your machine and report
1. FW version you think you were running on tinyG (440.20 is most recent)
2. CP or Coolterm? If CP, what version of SPJS?
3. Were you running mature Gcode (has run before) or something new?
4. What upgrade technique were you using (CLI, SPJS updater, ?) ?
5. Your CP OS (Win, Mac, Linux) and your CP Browser (Firefox, Chrome,?) if CP user
Then keep you eye on the forum for developments, we already have a lot of input and folks are looking
just curious if OP (bvi8370) ever solve the problem?
reading the post his board was probably purchased around the same time as mine (mine shipped in july).... a bad batch maybe?
Same trouble!!!!! I have tried to download update but no verification. un plugged all motors switches and still just get a flashing light on sp dir.
Switched from a windows 64 to my macbook pro and no luck.
When I tried to update this is what came up...
No communication
tinyg updater
This also came up on another try
uncaught exception

Check back tonight, I believe the devs are close to a diagnosis for this situation
BTW, read this, I am suspicious that you are in same boat
.Has this issue been solved yet? Im still waiting to hear back and was told to wait because i could do the fix myself instead of sending the board back for a replacement. Its been 6 days now since i have had any contact. I was told that there would be a write up before ril3y gets the boads to look at and i could test to see if it fixes the problem but ive herd nothing since.
damn mine just joined this club too. i should have just stuck with my old firm ware. i installed the bootloader and that went all fine and dandy. now it stays in the boot loader permanently with the flashing light

Its not really a good idea to stay behind in FW unless you have a very repetitive job that just works, and the fuse setting issue (if that is your problem) could affect any FW build.
