I suggest you connect to the board via USB and send M552 to see whether the WiFi module has connected to the access point.by dc42 - Firmware - experimental, borrowed, and future
I just looked at your tuning results again and it appears that the heater power is too low to reach the target 200C. That points to a bad heater cartridge, bad connection, or low power supply voltage. It could also mean that the temperature sensor is greatly under-reading, however that should not be the case if you are using a PT100 sensor and you get the correct reading at room temperature.by dc42 - Delta Machines
You need to run firmware that supports Rotary Delta kinematics. RepRapFirmware does, see . Maybe there is a fork of Marlin that does. The calculations for Rotary Delta kinematics involve trigonometry, so you should use a controller with a fast processor and hardware floating point. Calibration can be tricky because there are so many parameters to set - not a problem for a well-manufactured commeby dc42 - Delta Machines
What is the hot end temperature limit set to? Send M143 H1 to check it.by dc42 - Delta Machines
It looks like the gain of the hot end heater has reduced and the cooling rate has increased. Were you perhaps tuning the hot end with the print cooling fan off last time, and on this time?by dc42 - Delta Machines
I can't comment on Marlin, however I think it likely that your ABL issues are caused by the combination of imperfect delta geometry and your use of a Z probe that is offset from the nozzle. Many types of geometric imperfection in deltas cause the effector to tilt slightly with XY movements. This tilt causes the relative height of the nozzle and the Z probe to change, which causes errors when youby dc42 - Firmware - Marlin

M666 sets the corrections to the endstop switch positions, not the actual locations. Please post your complete config.g and homedelta.g files. You will get faster responses to questions relating to RepRapFirmware if you post them at .by dc42 - Developers
I'm glad you got it working with RRF. BTW, the latest RRF 3.2RC tunes with the print cooling fan both off and on, so that it can apply feedforward corrections to the heater power when the fan speed is changed.by dc42 - General
The tolerance on typical Chinese heater cartridges is very wide. You need to re-turn the heater after changing the cartridge, even if the new one has the same nominal power.by dc42 - Delta Machines

Latest version is 1.26.1 available at . Caution: you may need to make some changes to your config.g.file, in particular to make the X axis move the right way and to configure the endstop switches. Support is available at .by dc42 - Huxley
If you are using RepRapFirmware then the Z position when homed is set by the H parameter in the M665 command. See .by dc42 - Firmware - mainstream and related support

The new Duet 3 Mini would be a good match. It's available in WiFi and Ethernet versions. A few Duet3D resellers have them already, and more will have them next month.by dc42 - General

This is why we implanted feedforward heater control in RepRapFirmware.This temperature plot shows the effect of turning the print cooling fan on at about time 18, and off again at time 106. To reduce the amount of temperature drop, use a silicone sock on the heater block, and make sure the air is directed at the print not the nozzle or heater block.by dc42 - Delta Machines
Thanks for pointing out the error in that paragraph. I will correct it. Further down in that page under "Homing files", it says: QuoteFor each of the proximal and distal joints, you should have a homing switch either at the maximum limit (maximum anticlockwise angle as seen from above), or at the minimum limit (maximum clockwise angle). In your M574 command in config.g, for the proximal point uby dc42 - Polar Machines, SCARA, Robot Arms

Due to lack of space I am selling my Ormerod 1.

Most likely you have a weak PSU or a bad VIN connection, so that every time you tried to move the motor, the VIN voltage dropped below the minimum. The Trinamic drivers don't work below about 11V. You can compile RRF with HAS_VOLTAGE_MONITOR disabled.by dc42 - Firmware - mainstream and related support
Do you actually need bigger motors? Might turning the current down be a solution? I don't know of any separate TMC5160 driver modules not in stepstick format other than the Trinamic evaluation board. Perhaps someone makes one in Bigfoot format.by dc42 - General
We're telling you to buy a modern controller board that is not Arduino-based and is 24V compatible. Preferably a Duet, but I'm biased - see my signature.by dc42 - General
Nema 23 steppers are not that big, and properly designed , mounted and heatsinked TMC5160 drivers with their external mosfets can easily handle more than 3A. But not stepstick-format drivers. Get yourself a better controller that is designed for high current motors. Duet 3 will drive Nema 34 motors at up to 4.5A RMS, 6.3A peak.by dc42 - General
