RepRapFirmware 1.19.2

This release implements bug fixes and minor improvements to the 1.19 release.

IMPORTANT! Before upgrading to this release, read the important upgrade notes in the WHATS_NEW file (https://github.com/dc42/RepRapFirmware/blob/dev/WHATS_NEW.md) . You will also find the list of all the new features and bug fixes in the same place.

EDIT: I updated the DuetWebControl.zip file to 1.19.3 on 2017-11-06.

RepRapFirmware 1.19

This release supports auto bed levelling using multiple leadscrews, resume after power fail, SCARA kinematics support, and many other new features too numerous to list here.

RepRapFirmware 1.18.2

New features since 1.18.1:

• Duet WiFi and Duet Ethernet build now recognise new production DueX2 and DueX5 expansion boards, and support Fan 8 on the new DueX5

bug fixes since 1.18.1:

• M21 command did not properly re-initialise the file system
• M42 commands are now synchronised with movement
• M106 command allowed the fan number to be one higher than the maximum supported

RepRapFirmware 1.18.1

New features:

• First official release for Duet Ethernet
• M204 is now implemented (P and T parameters only)
• M997 command now checks that the start of the main firmware file looks sensible
• The rate at which "No tool selected" and "Attempt to move before homing a delta printer" messages are generated is now limited
• Added VSSA fault detection if the hardware supports it
• If there are too many probe points implied by a M557 grid definition command, the firmware displays a suggested increased spacing
• On the wired Duets, M586 can be used to set which network protocols are supported and which port numbers are used. By default, http is enabled, ftp and telnet are disabled.
• Baby stepping is now implemented using the M290 command. The accumulated baby stepping amount is reported in M408 replies.
• Faster and easier-to-use auto tune algorithm with more consistent dead time measurement
• M109, M190 and M191 commands now send the temperatures once a second if the command came from the USB port and Marlin emulation is chosen
• The name of the firmware file to load is now passed to IAP, so that iap4e.bin can be used on both the Duet WiFi and the Duet Ethernet
• Added code queue so that fan commands etc. are synchronised to movement (thanks chrishamm)
• Added chrishamm's input buffering code (thanks chrishamm)
• Reduced the Duet WiFi VIN over-voltage detection threshold from 29.5V to 29.0V
• Live coordinates are now reported to 3 decimal places instead of 2
• When using a Z probe type other than 2, the probe output is sampled every 1ms instead of every 2ms for faster response
• PanelDue status responses continue to be sent while executing M109/116/190/191 commands
• Increased maximum permitted motor current on TMC2660 drivers to 2.4A
• Improved error messages when a M303 command has an out-of-range parameter
• We now use a USB VID/PID allocated to us instead oif Atmel's CDC example ones
• The Windows device driver now supports the Bossa Program Port, so you can now use bossac even if you don't have the Atmel or Arduino device driver for it installed

Bug fixes:

• Fixed issue with loading height map file when the number of probe points along the X axis is large
• Interpolation near the edges of the bed was incorrect when mesh bed compensation was used (thanks ChristophPech)
• On the Duet WiFi, if you sent command M122 while the machine was printing then occasionally it would stop and reset due to a watchdog timeout
• If multiple input sources sent overlapping G4 (dwell) commands, either or both of them would not be executed correctly

Other changes

• M552 no longer includes the option to set the HTTP number. Use M586 instead.
• M557 P parameter to set probing points is no longer supported. Use a bed.g file instead.
• Temperatures default to 0C instead of -273C

Known issues

• If you enable tool mixing, you should use relative extrusion only. If you use absolute extrusion, then if you pause and resume the print, the extruder is likely to extrude the wrong amount of filament in the first move after resuming.
• If you use M586 to disable FTP or Telnet on the Duet 085 or 06 after you have previously enabled them, the firmware refuses new connections but does not terminate any existing connections.
• FTP on the Duet Ethernet cannot be used to do file transfers

Upgrade notes

• If you connect via USB from a Windows PC you should install the updated device driver in the Drivers folder of this repository
• If you use the M552 R parameter to change the HTTP port number on a wired Duet, you will need to use M586 instead
• If you use FTP or Telnet on a wired Duet, you will need to enable them using M586
• It is recommended that you re-run heater auto tuning when upgrading to 1.18 from an earlier release
• You may find that your Z probe trigger height is slightly higher than before, so you should re-measure it
• When upgrading to this firmware, also upgrade iap.bin or iap4e.bin to latest version
