Code: Select all
Setting bed temperature to 60.000000 degrees Celsius.
Error:Heating failed, system stopped! Heater_ID: bed
[ERROR] Error:Heating failed, system stopped! Heater_ID: bed
echo:Heating Failed
Error:Printer halted. kill() called!
[ERROR] Error:Printer halted. kill() called!
Disconnected.
Wondering if its because I started at 28c :roll:

Setting the bed at 60c.. The heater comes on for a bit and hits 47c, so way off.
On the status..

10/60 10 is what's in the file, and 60 is the set temp and 3685, then 3642 shows the sensor lowing in value.. sooo..
Code: Select all
{ OV( 3570 ), 54 },
{ OV( 3600 ), 52 },
{ OV( 3657 ), 51 },
{ OV( 3687 ), 48 },
{ OV( 3724 ), 46 },
{ OV( 3752 ), 43 },
{ OV( 3816 ), 38 },
{ OV( 3863), 31 },
{ OV( 3876), 29 },
3642, well 3657 51c.. close enough.. but nope, 47c not 51c... :WTF: and pronterface still showing 10c anyway.

A possible thing is its actually set to 10bit resolution :roll:
Code: Select all
#define THERMISTOR_TABLE_ADC_RESOLUTION 10
#define THERMISTOR_TABLE_SCALE (HAL_ADC_RANGE / _BV(THERMISTOR_TABLE_ADC_RESOLUTION))
#if ENABLED(HAL_ADC_FILTERED)
#define OVERSAMPLENR 1
#elif HAL_ADC_RESOLUTION > 10
#define OVERSAMPLENR (20 - HAL_ADC_RESOLUTION)
#else
#define OVERSAMPLENR 16
#endif
#define MAX_RAW_THERMISTOR_VALUE (HAL_ADC_RANGE * (OVERSAMPLENR) - 1)
So 10bits for 3000+ values falls a bit short... Well 2 bits :lol: :roll:

Yep that was it. 12bits and now things are working as expected :dualthumbup:
43.16 / 43.00 and 43 on the bed :D

Now to see if any tables will work with my extruder..

Having noticed the stock is running low on STE DUALTOS boards. I was considering getting the batch made up of these boards again..

But later on forgot that some years ago I did this board..

I think they were basically discontinued because the UBE circuit never was reliable and I did not have the time to solder the SMT sockets.
Though I am thinking of just removing the now-defunct UBE part and is producing those smaller more compact boards with the SMT socket. I'm hoping they will be much less outlay for me to get them into production.

I'm still constantly chugging away in the background working on store items. For example today I am testing CPU's and DRAM. yesterday I was mostly working on ROM's.
A lot of items in my store are going out of stock. Basically because I am yet to invent the 5,000 hour day yet. But a lot of projects are being transferred over to the company which built the H5 motherboards for PCB and assembly. There will be a bit of a crunch when all this stuff turns up at once. So maybe sporadically quiet but working hard in the background to keep the items flowing in my store for people.

EDIT:
Looks like some projects starting to come into fruition

I saw from your stock thread that you've started doing the naked STE dual ROM boards. At £6, that's an absolute steal and I shall be investing for my next order. Many thanks.
