Well, I have been unable to fix the problem, and am out of patience. It seems to only occur when in motion. It is not the thermistor, I changed that. It is not near-by wires, I put external wires on it that did not go near stepper wires. It seems unlikely that it is power because channel one never drops out and I am using a 360W power supply. So, I will change the beast back to a single head Vby dlc60 - Reprappers

QuoteTshawkins that is exactly what I did, i had already inserted a central 2020 strut, so i could shorten the filament path in the bowden tube, so i used a little 2020 stock left over to create a bar with a post on it that is used to tension the belt. Works really well. The only caution is that the motors are not very rigidly mounted and will rotate around the plate they are sat on. so if the teby dlc60 - CoreXY Machines
QuoteRecoil1980 Sorry I am just getting back around to responding. I eventually sent the printer back. I think the sensor was just bad, then the LCD screen went white and I was unable to use it at all. I spend the extra money and got an Ender 5 Plus. So far the new one is running, but there are still a few issues with it. No big. I figured it out. I have never liked the inductive sensors anby dlc60 - CoreXY Machines
It was a pretty common practice in RC car racing to place .1uF caps between each motor tap and the metal housing and one between the motor taps with DC brushed motors. This eliminated a raft of issues with PWM motor controllers. So, yeah, it helps with DC brushed motors. I don't know about brushless motors however. DLCby dlc60 - Firmware - Marlin
Quoteheavy9 It's very frustrating With a very light touch. try to "cant" the screw a bit diagonal so that the threads catch in the plastic and oh so lightly back it out without pushing inward. It is a finicky thing to do. We've all done that at least once. Sometimes you can get a needle-nose pliers in there to grip the screw and pull.

I use XT-30 connectors. I used to use XT-60s, but they are too bulky. The XT-30 are small, truly low resistance and pretty easy to remove. I do all of my hot-ends with these so that I can remove them easily to clear or replace them. I have one printer that I have 5 different heads that I use on it. DLCby dlc60 - General
Are you still using the Chitu board? I am still running the TronXY firmware on the board after removing the prox sensor, adding a borosilicate glass bed and the Z-stop sensor. I also moved to an E3Dv6 hot end and am considering a move to a Hemera. I got my X5SA Pro in March 2020, and they are known for changing controller hardware on a whim.

Concrete is not a very "green" material to work with however. "Perfect" concrete requires a particular sand, which we are running out of.

After talking with the Exoslide guy and changing my hot end mount to give me space for a fourth slider on the hot end mount. I think that I have solved the problem. My issue always occurred during a high speed transition in the X axis, which caused me to focus there. BUT I forgot that in a CoreXY machine, every transition affects every axis, X and Y are linked and must cooperate, so, even thougby dlc60 - CoreXY Machines
Quotethe_digital_dentist DLC60, if it's printing square you're done. The X and Y axes are square. The error may be in the frame which doesn't really matter. Yeah, that is what it looks like. I guess that I can live with just printing slowly if parts are "perfect". Now, if I can just figure out why I get the jams at high speeds then I'd be in printer heaven! DLCby dlc60 - CoreXY Machines
Quotedustinoff Quotedlc60 I printed a 40mm cube, and it was square, and very close to 40mm on each axis. DLC measuring each side does not tell you it is square. You must measure the diagonals. "square, and very close to 40mm on each axis" means it is square (56.56mm on the diagonal, pretty much dead on) AND 40mm on a side. Commas matter. DLCby dlc60 - CoreXY Machines
Quotedustinoff Quotethe_digital_dentist If the frame is square it works fine. if your frame isn't, all bets are off. Well, isn't the question about how to determine squareness. The only way to do that, other than a lab instrument to measure 90°, is to measure the diagonals. But on printer hardware, measuring two diagonals accurately seems to me to be pretty difficult. The easiest thing one can dby dlc60 - CoreXY Machines
Quotethe_digital_dentist The way you know if the belt tensions are correct relative to one another is that the X axis is square with the Y axis. The absolute tension is another matter- it should be tight but not too tight. In my printer the belt tension is adjusted by sliding the motor mounts back so I get a direct feel for how hard I am pulling on them. If your belt tension adjustment uses a scrby dlc60 - CoreXY Machines
QuoteRockyAussie To Quote - I am quizzing the Exoslide guy about this, I am using Exoslides for my X and Y axis I have looked at the design of these on the tube over and over and I have to say I would be quite concerned about having so many rollers continually running along soft and sometimes dirty aluminium. I have seen some applications where running 3 rollers has worked better than 4 let aloneby dlc60 - CoreXY Machines
If you have a heated bed, that 5A supply will not be enough. Heated beds draw 9+ amps, I have one that draws 12Amps. If you are powering the hot end at the same time that could add another 3 Amps. And, you want margin (more capacity than you need) to handle surge currents. Power (Watts) = Volts X Amps. In general, you want a 50% margin. So, if worse case here we have 15 Amps at 12V that isby dlc60 - Delta Machines
QuoteRockyAussie I noticed that de42 had suggested dropping your z acceleration speed and am wondering if you had tried that and by how much? I had a bit of an issue with the Tronxy x5sa pro when I increased the overall acceleration speed (M8008) from 100 to 700 and the Jerk (M8007) from 20 to 10 and that resulted in a total stop when the head went from front left to rear right and the z started.by dlc60 - CoreXY Machines

QuoteOhmarinus You could also raise the steps/mm of the extruder motor Good point.

Try looking at the problem a different way, you have more than one knob you can adjust. Set your nozzle size to something like your actual one. Then play with print speeds, flow rate, layer width and extrusion multiple. All of these can be tweaked separately on CURA, on S3D, you only get speeds, layer width and extrusion multiple.
