@Surgikill possibly. i've not used M99

@deckingman

Fantastic question. I am using CNCKitchen's Blob Test.

I had to modify an excel sheet i found online to make it work for a delta printer

Would you be willing to share the modified sheet, or just explain what needed to be changed? I run a delta and this is testing I need to do 🙂 (EDIT: actually, scratch that, I figured out quickly what needs modding and I'm already done. It didn't have a round bed mode, mainly.)

@dc42 Does feedforward only work in job files? Should I expect it to work in macros or via the interface buttons?

@fcwilt ,

Mmm, Lamb Tagine

@Phaedrux ,

Thank you for that. I'll read up on this.

@engikeneer @jens55 I rebuilt the hot end and replaced the droopy fan mount I'm running a tune now and everything seems to be going smoothly. Thanks for all your help!

@TOFUATSU the commands are not printer dependent but the ones I quoted were from a CR10-S5, 500 x 500, cartesian, bed slinger

@jens55 The extra weight of longer belts on a core XY is insignificant as is the weight of the moving idlers when compared to the moving mass of a "bed slinger". Couple that with the fact that both motors contibute to motion for anything other than 45 degree moves and the 1.4 gearing effect on those moves means that a CoreXY will always have more torque available than a Cartesian. The only exception might be 45 degree, single motor, high speed moves where, because of the gearing effect, the motor turns faster and could potentially reach the point where the torque curve starts to drop. But it would need to drop to the point where the torque is 1/sqrt2 of peak torque where it might become an issue. On my machine, with my motors, that's about 550mm/sec.
By way of an additional data point, I used to have 6 extruders mounted on a second (UV) gantry above the XY gantry. The moving mass of this set up was circa 3Kgs which I could accelerate at 2000m/sec^2 up to 350mm/ sec using a pair of Nena 17s with quoted torque of 59Ncm..

Furthermore I saw that this component (in the following picture) is broke. Where can I buy it?

@deckingman In my case, I designed the duct myself for my custom printhead. I ran CFD on it, so I'm happy with where the air is directed. But the CPAP fan at full speed is in another league compared to normal part cooling fans, so there is only so much "containment" of air flow we can do. See the first 15 seconds of Vez3D's video on it. https://youtu.be/E3kBau82SwU?si=skFc90h_gz5UPpWB

He is running his at amazingly high speeds, and even uses extra blowers that direct air from the sides of the print area, which he needs for the high speeds he is running. See this video, it's absolutely astonishing. https://youtu.be/hcMxEkVvIdE?si=Zz3FRlIIbShGoVR1&t=580

So I don't think there is any other option than to use these high powered fans.

I'm running things a bit slower, so I don't need the full power at the moment. But it's nice to know it's there if I do, or if I decide I want to print PLA.

Thankfully the there's no aluminum in the hotend, it's full copper and nichrome. Although the silicone sock would be problematic. The heatbreak is water cooled, so as long as the pump doesn't stop at the same time, the aluminium above the heatbreak wouldn't melt.

@sinned6915 said in Euclid probe unnecessary docking:

Lastly, you might notice why the Euclid examples do not check the check the OM probe variable for deploy: we check the actual probe value to ensure pickup in case of a mis-deploy.

sinneD

So you have a new version of the probe where the presence/absence of the switch can be detected?

Thanks.

Frederick

@droftarts thank you for your help.

I finally got the following result:

@Jack What are you measuring with the "external thermocouple"? Please give specifics of the actual temperatures measured. So for instance is it simply room temperature or the temperature of a hotend? If it is a hotend where have you placed the "external thermocouple" a photo showing your test setup would probably help.

@Reine the frequencies of Z vibrations are quite high, so they may well be caused by something other than ringing e.g. a fan.

@dc42 Ok interesting so for now I will just comment out my homez file and finish writing my homeall file and once that is done it should no longer run homez after. Thanks!

@infiniteloop You still miss the point. The DC UPS is just that - the (7Ah) batteries only cut in when mains power fails and will keep the machine running for over an hour. I never said that I use a 2Amp power supply. In fact I still use the much larger (Meanwell) DIN rail mounted supply that I used when the machine had 7 axes (CoreXYUVAB) and 6 extruders and a two zone hot end with two 80 Watt heaters. My point remains that most people over estimate the power requirements of their machines and waste money buying an over-specified PSU. For sure, leave some head room for future expansion, for sure use a quality PSU, but one that is capable of supplying 4,6,8 or 10 times the required power is a waste of money and can be dangerous because it might not trip if a fault on the machine develops.

@tylersuard if you use 3.5 series firmware then with the Duet3D magnetic encoders you don't need to do the calibration every time, only when the relative positions of the encoder board, motor shaft and magnet may have changed.

@Tricep-terry currently if a command that has axis parameters such as G1 refers to axes that don't exist, those parameters are ignored. In a future version of RRF we may generate warnings when a command has unused parameters.

@dc42 Ok thank you, I will try that!
