My Delta was printing fine.
This morning I switched it on again after a few days of no activity.
Now all thermistors read 2000C. All three of them. The bed, the hot end and a testing thermistor for sensing water temp.
What could be the cause?
I checked the wiring, all are still connected. Besides, it is all three at the same time.
In the middle of designing a part cooling solution for the Smart Effector. A customer was asking for a 5015 fan duct that will handle a Volcano. I went a little further and this design will handle both a normal V6 and Volcano.
The one worry I have is if this fan brace will interfere with the bed sensing capabilities of the Smart Effector.
The only place where the brace touches the PCB is around the ball bolts. As I don't have a Smart effector (yet) does anybody have an opinion? Thanks.
Hi Tony,
Nah, it is just that because I have 0,0 set in the center, and not left front, it comes out a bit strange, but it works nicely.
To pick up a tool, in the toolchange macro, I have to go outside the print boundaries. Now I do that with a relative statement with the S parameter set. It works, but is there a different way to do it?
Man I could kiss you!
Yep, that solved it.
I can now move everywhere at speed with no S parameter.
Thank you.
It still feels odd to define Z300 as minima and Z0 as maxima but it does the trick.
OK now I can continue with the real tests. Thank you again.
No, didn't make any difference.
It is consistent. Everything I try doesn't make any difference.
Since I don't have any of that connected yet, not even the Z stepper, I think I will comment it all out and reduce the config file to the absolute minimum.
It is a normally open switch.
I have downloaded the combined file and installed that.
Nothing I do, makes a change in the behaviour.
Even with no endstops connected, I still have the strange movement. It will only move at speed if I add the S1 or S2 parameter. Otherwise it is crawling at a snails pace.
I have confirmed that the endstop plug is wired correctly. All leads go into the correct connector, both on the endstop and on the board.
The fact that the LED on the board is on, when the endstop is NOT triggered makes me think there is something wrong in the config. But I cannot work out what is wrong.
Unless it has absolutely nothing to do with the endstops. But then it is even more strange behavior.
One more thing, I have updated the firmware to the last version, so I am thinking hardware/config.
Yep, With the S1 in the G1 statement it moves nice and quick.
Without, it is very slow.
All this is in the Gcode console.
This is the end stop used:
Clearly it has something to do with the endstops. THey are a bit different than what I normally see. The LED on the Duet board is lit while the end stops are not touched, and go off when they are. The green led on the end stops then goes on.
Now I assumed, red is V3.3, black is ground and white is signal. That is how I wired them.
Something strange is going on here.
When I run a macro with the following code:
G1 X150 Y150 F3000
It runs extremely slow.
When I run
G1 S1 X150 Y150 F3000
It runs nice and fast.
It seems the S parameter has some unexpected results?
I am running version 2.0 Build 2018-06-05b3 and web interface 1.21.1
Thanks Tony,
That is what I thought, just wanted a sanity check.
Although in my case sanity is probably a wrong word.
Hi all,
After some reading, I am wondering if I should use stall detection for my homing process on the CoreXY I am designing.
It needs to be a very accurate homing position, so is it the right choice? With enough tweaking can I get to a high degree of repeatability, or should I decide now to go for sensors instead?
As I am still designing, I can probably find the space to place sensors. If I have to add them later, it might be more difficult.
Man oh man, am I happy with this stuff!
Just received my new Duet board and I have to say, setting it up is so easy! Made a config at https://configurator.reprapfirmware.org/ and downloaded the zip file. Uploaded it in the Duet and presto! One running system.
Thank you guys!
In case (pun intended) anybody is interested in a little PanelDue housing for the 5 inch version, here is one intended for a CoreXY with a heated chamber.

It will fit in a cutout in the door, and will swivel out for the optimal angle.
On my crappy multimeter, it starts at 0.28 amps and settles on 0.3 amps.
But I don't think my meter is quick enough to accurately measure the starting current. I will see if Brian can measure it.
But at least the rest of the config is correct, yes?
Currently, I have it on a direct 12V external power supply.
I noticed that when I switch it in, it starts up slowly.
Does that tell you anything?
