New 20.22W firmware for WD-20 mount available now. Introducing new AEB (Automatic Emergency Brake) tuning feature and process, which makes it more easier for adjusting aggressiveness of AEB protection.
For upgrading to new features, please refer to firmware flashing guide link. Any questions during upgrading please contact our support team.
Attention - availability of firmware
-
Mount already running on 20.21W can be upgraded to 20.22W directly, including manufacturing date started from Oct 2024.
-
For firmware version old than 20.21W(e.g. 20.12W), please check motor version by using Motor Tool, motor version must be upgraded to version 236.
New features
1. AEB(Automatic Emergency Brake) Auto Tuning
- AEB auto tuning process now available, aggressiveness and threshold can be measured by cooperating with PC Mount tool automatically. For much easier and faster process to set an adequate aggressiveness to avoid AEB too sensitive triggered that may interrupt a normal operation, and providing responsive protection at the same time.
2. Supporting PC Mount Tool V1.0
- AEB auto tuning process.
- Status and error monitoring.
- New motion control functions, including Max Goto/slewing rate and guide rate settings.
- GPS modes adjustment available.
- PID Level customized.
Improvements
- Thermal management system optimized, for possible extreme temperature low operation ability under -30℃(experimental)
- AEB default sensitiveness optimized.
Bugs fixed
- EC Guard HA Limit may block operation in ALT/AZ mode - Solved.

Firmware Flashing Guide
20.22 firmware require motor firmware version running at 236. Before flashing firmware 20.22, user must follow below instruction and applied to the steps required accordingly.
Step 1 - Check current mount firmware version
- Firmware ver can be read via WarpAstron PC Mount Tool or Hand Controller(Settings->Ver.)
- Mount firmware version 20.21W - User can flash new 20.22W firmware directly by using ESP Tool. Including manufactured date started from Oct 2024.
- Refer to link below for downloading.
- Mount firmware version 20.12W - Please follow Step2
Step 2 - Check current motor firmware version
- Download WarpAstron Motor Tool from official website.
- Flash Service Mount Firmware to mount via ESP Tool.
- Use Motor Tool to connect the mount and check the motor versions
- For motor version = 236, user can flash new 20.22W firmware directly.
- For motor version = 235, user must upgrade motor firmware - Please follow Step 3
Step 3 - Upgrade motor firmware
- Download motor firmware(refer to link below) and complete motor flashing. Detail instruction refer to video guide below.
- Attention - User must read instructions in tool folders carefully and follow all steps required during motor flashing sequence, otherwise the motor may stuck in flashing mode, and a remote support need to be schedule to recover it.
Note:
20.21W firmware will be no longer available for downloading, replaced by 20.22W

AEB Auto Tuning Guide
Introduction
AEB(Automatic Emergency Brake) protection feature in mount designed for emergency stop and reverse the mount, when detecting collision happened based on servo motor monitoring. AEB will use parameters AEB aggressiveness ratio and Threshold during calculation and monitoring. If parameters configured too sensitive and may abort normal operations. User need to adjust parameters based on the OTA or other conditions. For more understanding of AEB feature, please visit: WD-20 20.21W Firmware Upgrading Available - Introducing New Safety Features - #3 by Technical
AEB Auto Tuning feature can help user set most adequately parameters for their OTA/load. To make the tuning process much easier by just press start and waiting for auto process completed.
NOTICE
1. Mount will rotate to EC HA Limit position, which is close to the tripod or pillar that could cause collision during this process with default factory value 95 degrees. User must set EC HA Limit firstly based on the situation of the OTA and tripod that used, ensure position of EC HA Limit will not contact with tripod etc.
2. Emergency brake and reversing will be disabled during ongoing auto tuning process. User must stand by with the mount for emergency abort this process if on the way to a collision to tripod.
3. Check positions of cables, camera, filter wheels etc. To avoid collision between them and tripod during the process.
4. Power supply must meet 12V 5A, or with higher current capacity, as mount require more power during high speed slewing.
Preparation
- PC (Windows) with CP2102 COM port driver installed.
- Download WarpAstron PC Mount Tool.
- Install OTA on the mount.
- Contact mount to PC via USB cable.
Evaluate Collision Risk
Step 1 Check current EC HA Limit
- Power on the mount and open WarpAstron PC Mount Tool.
- Connect to mount by selecting COM port and Connect.
- Go to Tab “Safety & Limits”
- Click “Read All”.
- Default EC HA Limit will be 95 degrees to East and West. Check if any collision risk if mount rotate to that positions.
- Modify the value and click “Write” and “Reboot” to save it.
Steps 2 Check collision risk on EC HA Limit position
- Go to Tab “Motion”
- slew rate to “1/2 Max”
- Click “East HA Limit” or “West HA Limit” to rotate mount to that position.(Mount must be at home when doing this, click “Return Home” for homing.)
- ABORT the motion/slewing when collision could happened during this.
- Modify the EC HA Limit value if required and test again.
Auto Tuning Process
Once EC HA Limit confirmed safety for the rotation towards tripod, user can continue following AEB Auto Tuning Process.
Brief of process
- Prepare - Checking mount if already at home
- Go Home - Mount will return home if not at home
- Slewing - Slewing to East EC HA Limit position
- Homing - Return to home
- Completion - Display threshold result and set to mount
Button introduction
- Start - To start the process
- Stop - To stop the process
- Abort - Abort ongoing process and stop all motions
- Close - Close tuning window, any going process will be aborted
Step 1 - Prepare
- Install your OTA to mount.
- Ensure EC HA Limit has been properly set to avoid collision at East and West positions.
- Go to Tab “Safety & Limits”
- Click “AEB Auto Tuning”, Tuning process window will be open.
- Click “Start” to begin the process
- For any emergency stop required during the process, please click “Abort” button.
Step 2 - Go Home
- If mount already at home, this step will be skipped automatically
- If mount not at home, mount will slewing back to home and recheck again.
- If homing failed after 2nd trying, process will be stopped.
Step 3 - Slewing
- Mount will slew to East EC HA Limit position, which is close to the tripod. Rotated angle will be ‘EC HA Limit’ degrees from home position.(95 degrees in factory default)
- NOTICE - User must monitoring this rotation and ready to abort it, in case EC HA Limit not been properly set based on actual situations.
Step 4 - Homing
- After reaching the East EC HA Limit position, mount will then return to home.
Step 5 - Completion
- Mount returned to home position.
- Once threshold been calculated successfully, the process will display Threshold Max value and write to mount automatically, with default aggressiveness = 3.0.
- Reboot the mount to take effect.
Note:
Threshold base value measured depends on specific OTA/Load, once OTA/Load changed, user need to redo the AEB tuning process. Read more about AEB conditions for reference.
Video Introduction
Um… The download links don’t seem to link to anything (they are not links). How do I get the new firmware and mount tool?
The download links I agree do not link at all… but the W20.22 is available on the WD20 mount description, mid way to the bottom of the page in the documentation / software pane, you can see there the W20.22 file.
BUT
when it comes to PC Mount Tool V1.0, when you download from the support / software and drivers section , THE OLD 0.1 downloads, but not the new 1.0 version. WarpAstron , could you add the proper link for 1.0 please. Thank you.
I will repost this message in the Discord page also… Thank you… Luc
Hi,
Releasing of 20.22 firmware is pending, once related instruction docs ready it will be online and available.
Update - Already released.
WarpAstron Support
Thank you very much so far.
FW update has worked.
But AEB tuning was canceled after trying to return to the home position.
The preset parameters (HA limits etc. are correct so far).
Any ideas?
Hi,
The mount will have 2 attempt for returning to home after step3, did you noticed mount moved when status message show returning to home?
Please submit a ticket for providing more info like videos to our support mailbox, or contact our support in official Discord channel if support online.
Thanks.
