Hello All,
I just wanted to share the successful result:
The only target for me right now is filament detection. 5 kg filament consumed so fast with no sense.

Hi, here is the link of the video of breef info about components and measurement proof of belt teeth .
Youtube Link: for the homing calibration and teeth
@dc42 Thanks for the support. Unfortunately, I am in quarantine. As soon as I finish it I will try again.
@dc42 Hi
Yes, it is 10 mm pitch and revolution 140 mm I have just confirmed steps/mm was correct. During the homing, as soon as the first or second limit switch engaged, the last motor slow down almost 8 times. and homing failed. One or a few pass then homing success.
This is the video about the issue.

@dc42 it is actually 10 mm. Because it is 3 meter high that's looks small.
Hello All,
Dyze-Design typhoon hot-end brief info:
I had a very difficult time getting it to work Dyze-Design typhoon hot-end.
The heating block long and high-density plastic extrusion capacity one of the highest in the range. IT can extrude 1 kg per hour, heating up to 480 celsius with no problem. The heating block contains two individual heaters and two sensors to maintain the temperature on the long tube.
The problems we faced in the beginning:
Therefore complication starts.
The solution for now temporarily:
Suggestion by David(@dc42)
Tuning those coupled heaters may work better using the following procedure;
Set the M570 limits for those heaters very high.
Find some parameters that allow you to heat both heaters at once to the target temperature.
With heater #1 at its normal operating temperature, tune heater #2 with the target temperature equal to its normal operating temperature.
Now set heater #2 to its normal operating temperature and tune heater #1.
If you continue to get "Temperature rising too slowly" errors, the fix is to reduce the gain or heating rate parameter. That's the M307 R parameter in 3.2RC1 and later.
Therefore I have found the parameters as advised:
I have set M570 on the S parameter at 240 ( position in the config after the M307 and M950 parameters.
I have set the M307 parameters;
M307 H1 A550 C180 D2.0 S0.35 V24.3 B0
M307 H2 A550 C239 D2.7 S0.5 V24.3 B0
You may see the different S parameters which are PWM settings.
In conclusion; I realize the present Reprap time and delay-dependent on algorithms are not really efficient, some cases not sufficient too, especially for the industry and advanced systems like the Dyze-Design Typhoon hot-ends.
Because the heating material is not gained temperature linear in time. If you measure the temperature peak after the cut-off, the difference between peak and cut-off should be the main value of concentration. If the peak temperature above the target range, cut-in temperature could be reduced, or if the cut is below the target range reduces the PWM and increase the cut-in temperature just equal to or above the cut-in.
Therefore, by implementing this main opportunity;
I believe I know the way it should be, If you like, please guide or contribute that we achieve success.
Kind Regards
Serkan

Thanks, I will definitely try this one. However, can I backup the existing firmware?
@Phaedrux said in Giant Delta printer Slow Homing issue.:
Well if you're certain that tooth to tooth distance is 10mm then I guess that's that.
I have confirmed twice also in the video once, step/mm calculation is right according to the 10 mm pitch.
The Actual problem is on the last axis homing.
I will try to setup like a cartesian machine and try homing again.
@deckingman Not exactly all parameters provided by Dyze, because heaters on the same blocks influence each other, tuning was quite difficult and took many trial and time to find those settings. As far as I remember earlier time PID tuning was not possible together. I had to run one by one. if it is possible, I would definitely run PID tuning if it is possible to run together. However, bangbang mode especially on heated bed works problem free.
@T3P3Tony said in Cold extrusion even the one of the pair disabled:
@sozkan ok yes so those are defined as i would expect them.
It may be an issue with the temperature sensor, is it always sensor 1 that that has the issue? Maybe look at temporarily switching them?
I thought about, but Dyze made everything very tight with their pcb connection, It is impossible. However I have replaced the block completely with new ones, still the same.
@T3P3Tony said in Cold extrusion even the one of the pair disabled:
@sozkan are you saying both extruder heaters are in the same heating block? If so how do you have the tool defined? normally you would have that as a single tool, with multiple heaters.
Yes, two heaters on the same block with individual driver and sensors tool defined as single one as the dyze design`s recommended parameters :
; HotEnd
M308 S1 P"spi.cs1" Y"rtd-max31865" ; configure sensor 1 as PT100 on pin e0temp
M308 S2 P"spi.cs2" Y"rtd-max31865" ; configure sensor 2 as PT100 on pin e1temp
M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
M950 H2 C"e1heat" T2 ; create nozzle heater output on e1heat and map it to sensor 2
M307 H1 B1 S0.36 ; 2.5 mm;
M307 H2 B1 S0.51 ; 2.5 mm nozzle

M570 H1 P30 T30 S10 ; H heater, T tolerance degree, S second persist.

Dear Duet3D Community members and Admins,
Thankfully, I have successfully build and tuned nearly perfect situation a one of the largest Delta 3D printer with your contribution. We will build much more larger ones that present built was really good experience for us.
However, rarely having an issue in the middle of the printing one of the heater on the same heating core goes on emergency mode, eighter extreme or low temperature warning. But it is causing a big waste if happens.
The extreme temperature error as you may see in the photo that suddenly appearing and it disabling the one of the heater and continue printing with one! Since two heater set and specified in the config as single heating core it is cousing stress on the extruder motor and crushed the gears.
As you can see second heater shown 159.5 and printing stopped! Despite the one heater disabled, before stopping it, it continue printing until the second sensors shown low temperature. However during this time problems caused cold extrusion, drive gears and motors stress and and failed print output and few hundreds euros damage and several kilo waste of materials.
Things could be better if possible in firmware:
Could you please recommend what could be solutions to fix and avoid this problem?
I still could not figure out why it is happening!
I have tried:

RepRapFirmware
Hi,
This is the latest firmware. I have just updated.
Heater 2 strangely spiked 480 celsius. have noticed this on long moves. Is this not sensing sensors during the long gCode interpretation?
Hello again,
During the 30 hours printing again fault again. it says Heater 0 fault, but a fault on Heater 1. Temperature drop to 203 at Heater 1 with no sense.
I don't understand, The fault detection can sense temperature from the sensor! The algorithm cannot activate power on time!
Isn't it possible to re-test and continue printing later?
Hello All,
I just wanted to share the successful result:
The only target for me right now is filament detection. 5 kg filament consumed so fast with no sense.
@deckingman said in Disabling Heater Fault:
@sozkan What you describe is close to how bang-bang mode works. So you could try that instead of using PID (change the "B" parameter). It might be a better option for that particular hot end.
But IMO Dyze design are ducking their responsibilities by producing a device and not suggesting how to control it. The PID algorithm works fine for every other hot end - even those with multiple heaters ( as in my case using two heat zones, each with an 80 watt heater cartridge).
Hi, thank you for the all suggestions. I am very grateful. I simply change to B1 and a bit play with PWM. Now it works much more stable. Thankfully, the problem is solved now.
By the way, the 2.5 mm of dyze hot end seems cracked due to my last year's hard start trial. They say the resin-like leakage seems like occurred from the crack. Therefore, they suggest for return for repair.
Isn't that possible with an algorithm to play for real-time tuning?
like measured time 5 seconds at present or during the printing:
It seems simple and more functioning to me. Measured time is even completely unnecessary. if the temperature goes out of the limit, simply auto-decrease the duty cycle.
